The frequency-sampling method is used to design the frequency response of a filter directly.
In order to design a length-71 linear phase FIR bandstop filter that has stopband (π/3 < ∣Ω∣ < π/2) using the frequency-sampling method, follow the steps below:
1. Choose the sampling frequency as π, which gives a normalized frequency response in the range of [0,1] (also known as the digital frequency domain).
2. Determine the number of samples required.
Since this is a bandstop filter, it must attenuate the frequencies in the stopband by 60 dB.
The transition bandwidth is π/2 - π/3 = π/6, and the normalized transition bandwidth is (π/2 - π/3)/π = 1/6.
The required number of samples can be calculated using the following formula:
N = ceil((2 * 60)/22) + 1
where ceil is the ceiling function.
The resulting value of N is 7.
Therefore, the filter will have 7 frequency samples.
3. The frequency samples can now be determined.
Since this is a bandstop filter, the frequency response should be zero in the stopband and 1 in the passband.
Therefore, the frequency samples can be set as follows:
F(0) = 1, F(1/14) = 0, F(2/14) = 0, F(3/14) = 0, F(4/14) = 0, F(5/14) = 0, F(6/14) = 0.
4. Compute the impulse response using the inverse Fourier transform of the frequency samples:
h[n] = (1/N) * Σk
=0N-1 F(k) * e^(j * 2πkn/N)
where j is the imaginary unit and Σ denotes the summation from k=0 to N-1.
5. Finally, plot the resulting filter's impulse response h[n] and magnitude response ∣H(Ω)∣.
The plots are shown below:
Figure 1: Impulse response h[n] of the length-71 FIR bandstop filter designed using the frequency-sampling method.
Figure 2: Magnitude response ∣H(Ω)∣ of the length-71 FIR bandstop filter designed using the frequency-sampling method.

JK flip flop is constructed from T flip flop. (True/False).
The statement "JK flip flop is constructed from T flip flop" is false. This is because a JK flip-flop can be constructed from other types of flip-flops such as SR flip-flop or D flip-flop, but not from a T flip-flop.
A flip-flop is a type of digital circuit that can store a single bit of binary data (0 or 1) and can be used to synchronize and store data signals in digital systems. Flip-flops can be divided into four different types, including S-R flip-flops, J-K flip-flops, D flip-flops, and T flip-flops. T Flip-flop
The T flip-flop, also known as the "Toggle Flip-Flop," changes its output state whenever its clock input signal toggles from 0 to 1. It is formed by connecting the output of a D flip-flop to its input via an exclusive-OR (XOR) gate. The T flip-flop has a single input, which is the toggle input. The toggle input is the input which causes the state of the flip-flop to switch.

The step angle of a stepper motor = 1.2°. The motor shaft is to rotate through 20 complete revolutions at an angular velocity of 15 rad/sec. Determine (a) the required number of pulses and (b) the pulse frequency to achieve the specified rotation. (c) How much time is required to complete the 20 revolutions?
(a) The required number of pulses:
To determine the number of pulses required, we need to calculate the total angular displacement of the stepper motor for 20 complete revolutions.
Each revolution corresponds to a full 360 degrees or 2π radians. Since the step angle is given as 1.2 degrees, we can calculate the number of steps required for one revolution by dividing 360 degrees by 1.2 degrees:
Number of steps per revolution = 360 degrees / 1.2 degrees = 300 steps
To calculate the total number of steps required for 20 revolutions, we multiply the number of steps per revolution by the number of revolutions:
Total number of steps = Number of steps per revolution * Number of revolutions
= 300 steps/revolution * 20 revolutions
= 6000 steps
Therefore, the required number of pulses is 6000.
(b) The pulse frequency to achieve the specified rotation:
The pulse frequency can be calculated by dividing the angular velocity by the step angle. However, we need to convert the angular velocity from rad/sec to degrees/sec since the step angle is given in degrees.
Angular velocity in degrees/sec = Angular velocity in rad/sec * (180 degrees / π radians)
Let's calculate the pulse frequency using the given angular velocity of 15 rad/sec:
Angular velocity in degrees/sec = 15 rad/sec * (180 degrees / π radians)
≈ 859.437 degrees/sec
The pulse frequency is equal to the angular velocity in degrees/sec divided by the step angle:
Pulse frequency = Angular velocity in degrees/sec / Step angle
= 859.437 degrees/sec / 1.2 degrees
≈ 716.198 pulses/sec
Therefore, the pulse frequency to achieve the specified rotation is approximately 716.198 pulses/sec.
(c) The time required to complete the 20 revolutions:
To calculate the time required, we need to consider the pulse frequency and the number of steps for 20 revolutions.
The time required can be determined by dividing the total number of steps by the pulse frequency:
Time required = Total number of steps / Pulse frequency
= 6000 steps / 716.198 pulses/sec
≈ 8.37 seconds
Therefore, it would take approximately 8.37 seconds to complete the 20 revolutions.

A small industrial plant with a three phase 415V supply contains the following equipment:
(i) 20kW heating load at unity power factor (pf),
(ii) 10kW lighting load at 0.95pf lagging, and
(iii) 20KVA induction motor at 0.85pf lagging.
(a) Determine the plant's total real and reactive powers.
(b) What are the plant in-phase and out-of-phase currents? Draw the phasor diagram depicting voltage and current relationship.
(c) The plant owner has decided to install a capacitor bank for power factor improvement. What capacitive reactance per phase, connected in delta, is needed to correct the plant power factor to unity?
a. The total reactive power is the sum of the reactive powers of all the loads: 0 kVAR + 3.03 kVAR + 11.77 kVAR = 14.8 kVAR. b. The in-phase current phasor will align with the voltage phasor, indicating a unity power factor, while the out-of-phase current phasor will lag behind the voltage phasor, representing the reactive power component. c. Acapacitive reactance per phase connected in delta of approximately 13.03 ohms is needed to correct the plant's power factor to unity.
(a) The plant's total real power is 50 kW, and the total reactive power is 14.8 kVAR.
In this small industrial plant, the total real power can be calculated by adding up the individual power consumptions of each equipment. The heating load has a power factor of unity (pf = 1), so its real power is simply its rated power of 20 kW. The lighting load has a power factor of 0.95 lagging, which means it consumes 95% of the apparent power as real power. Therefore, the real power for the lighting load is 10 kW * 0.95 = 9.5 kW. The induction motor has a power factor of 0.85 lagging, so its real power is 20 kVA * 0.85 = 17 kW.
The total real power is obtained by summing up the real powers of all the loads: 20 kW + 9.5 kW + 17 kW = 46.5 kW.
To determine the total reactive power, we use the reactive power formula: Reactive Power (kVAR) = Apparent Power (kVA) * sin(θ), where θ is the angle between the current and voltage phasors. For the heating load, the power factor is unity (θ = 0), so the reactive power is 0 kVAR. The lighting load has a power factor of 0.95 lagging (θ = cos^(-1)(0.95) ≈ 18.2°), resulting in a reactive power of 10 kVA * sin(18.2°) = 3.03 kVAR. The induction motor's power factor is 0.85 lagging (θ = cos^(-1)(0.85) ≈ 31.8°), leading to a reactive power of 20 kVA * sin(31.8°) = 11.77 kVAR.
The total reactive power is the sum of the reactive powers of all the loads: 0 kVAR + 3.03 kVAR + 11.77 kVAR = 14.8 kVAR.
(b) The plant's in-phase current is 69.1 A, and the out-of-phase current is 25.4 A. The phasor diagram will illustrate the relationship between voltage and current.
In a three-phase system, the in-phase current is the current that is in phase with the voltage, while the out-of-phase current is the current that is out of phase with the voltage. To calculate these currents, we use the formulas:
In-phase Current (A) = Total Real Power (kW) / (√3 * Line Voltage (V) * Power Factor)
Out-of-phase Current (A) = Total Reactive Power (kVAR) / (√3 * Line Voltage (V))
Substituting the given values, we have:
In-phase Current = 46.5 kW / (√3 * 415V * 1) ≈ 69.1 A
Out-of-phase Current = 14.8 kVAR / (√3 * 415V) ≈ 25.4 A
The phasor diagram represents the voltage and current relationship in a graphical form. It consists of a voltage phasor and current phasors. The voltage phasor represents the line voltage, while the current phasors represent the in-phase and out-of-phase currents. The in-phase current phasor will align with the voltage phasor, indicating a unity power factor, while the out-of-phase current phasor will lag behind the voltage phasor, representing the reactive power component.
(c) To correct the plant's power factor to
unity, a capacitive reactance per phase connected in delta is required. The value of this reactance is 13.03 ohms.
To determine the capacitive reactance required for power factor correction, we can use the formula:
Capacitive Reactance (Xc) = 1 / (2 * π * Frequency * Capacitance)
Since the plant is operating with a three-phase 415V supply, assuming a standard frequency of 50 Hz, we can calculate the apparent power (S) using the formula:
Apparent Power (S) = Line Voltage (V) * Total Current (A)
For power factor correction to unity, the reactive power (Q) should be zero. Therefore, the required capacitive reactance can be calculated as:
Capacitive Reactance (Xc) = Apparent Power (S) / (2 * π * Frequency)
Substituting the given values, we have:
Apparent Power = 415V * (69.1A^2 + 25.4A^2) ≈ 40.44 kVA
Capacitive Reactance = 40.44 kVA / (2 * π * 50 Hz) ≈ 13.03 ohms
Hence, a capacitive reactance per phase connected in delta of approximately 13.03 ohms is needed to correct the plant's power factor to unity.

Using four letters and inversion bars over individual letters: de + e' + d'e' = AB'C' + C'AD'. Using four letters and inversion bars over individual letters: (a + b) + (a . b) = AB + AB' = A (DE Morgan's Law applied to the whole expression)
a. Let us first convert the expression d(de) + (de)e into individual terms: de + e' + de'
Let's use DE Morgan's Laws to get rid of the parentheses and simplify the expression. The DE Morgan's Law states that the NOT of a logical operator AND between two variables is the OR of the NOT of the two variables (with an inversion bar over each variable). Similarly, the NOT of a logical operator OR between two variables is the AND of the NOT of the two variables (with an inversion bar over each variable).We can use this law to rewrite the expression as follows: d(de) + (de)e = de + e' + de'= de + e' + d'e' (DE Morgan's Law applied to the last term)

False, drum brakes do not have the ability to automatically pump the brakes if wheel lock is imminent; this is a function of anti-lock braking systems (ABS).
True or False: Drum brakes have the ability to automatically pump the brakes if wheel lock is imminent, as long as the motorist continues to fully depress the brake pedal.False. Drum brakes do not have the ability to automatically pump the brakes if wheel lock is imminent.
Drum brakes work on a hydraulic system where the brake pedal, when depressed, activates the brake shoes to press against the drum and create friction to slow down or stop the vehicle.
However, drum brakes do not have the technology to automatically sense wheel lock or modulate the braking force accordingly.
Anti-lock braking systems (ABS) are responsible for detecting wheel lock and modulating the braking force to prevent it.
ABS is a separate system that uses sensors to monitor wheel speed and applies rapid, controlled pulsations to the brake system to prevent wheel lock and maintain steering control.

In C++, given two vectors of integers, with the same number of elements, write a function that will swap the contents of each vector.
For example, input vectors [1,2,3,4] and [5,6,7,8] will be changed to [5,6,7,8] and [1,2,3,4] up return from function call.
Here's an example implementation of a function in C++ that swaps the contents of two vectors:
```cpp
#include <iostream>
#include <vector>
void swapVectors(std::vector<int>& vec1, std::vector<int>& vec2) {
if (vec1.size() != vec2.size()) {
std::cout << "Error: Vectors must have the same size." << std::endl;
return;
}
std::vector<int> temp = vec1;
vec1 = vec2;
vec2 = temp;
}
int main() {
std::vector<int> vec1 = {1, 2, 3, 4};
std::vector<int> vec2 = {5, 6, 7, 8};
std::cout << "Before swapping:" << std::endl;
std::cout << "Vector 1: ";
for (int num : vec1) {
std::cout << num << " ";
}
std::cout << std::endl;
std::cout << "Vector 2: ";
for (int num : vec2) {
std::cout << num << " ";
}
std::cout << std::endl;
swapVectors(vec1, vec2);
std::cout << "After swapping:" << std::endl;
std::cout << "Vector 1: ";
for (int num : vec1) {
std::cout << num << " ";
}
std::cout << std::endl;
std::cout << "Vector 2: ";
for (int num : vec2) {
std::cout << num << " ";
}
std::cout << std::endl;
return 0;
}
```
Output:
```
Before swapping:
Vector 1: 1 2 3 4
Vector 2: 5 6 7 8
After swapping:
Vector 1: 5 6 7 8
Vector 2: 1 2 3 4
```
In this code, the `swapVectors` function takes two vector references as input parameters. It first checks if the vectors have the same size. If they don't, an error message is displayed, and the function returns early. Otherwise, a temporary vector `temp` is created to hold the contents of the first vector. The contents of the first vector are then replaced with the contents of the second vector, and finally, the contents of the second vector are replaced with the contents of `temp`, effectively swapping the contents of the two vectors.
In the `main` function, we create two vectors `vec1` and `vec2` with the given elements. We print the contents of the vectors before and after the swapping using a loop. Finally, we call the `swapVectors` function to swap the vectors and print the contents again to verify the swap.

The closed-loop transfer function of a negative unity feedback system is given by:
T(s) = S³ + 1/ 254 + s² + 2s
Find the systems using Routh-Hurwitz Criterion for Stability.
The given closed-loop transfer function of a negative unity feedback system is: T(s) = S³ + 1/ 254 + s² + 2s. Now, we need to find the systems using Routh-Hurwitz Criterion for Stability. Routh-Hurwitz Criterion The Routh-Hurwitz criterion is used to determine whether a closed-loop control system is stable or unstable. It is simple to use and avoids the need to solve a high-order polynomial.
Routh-Hurwitz criterion can only be used for systems whose transfer function has real coefficients. To construct a Routh-Hurwitz table, follow the instructions below: Make a table with two rows and as many columns as the highest-order term in the polynomial. The second row should contain only the coefficients of the even powers of the polynomial. The first row should contain only the coefficients of the odd powers of the polynomial.
The coefficients should be written in descending order. If any coefficient is absent, substitute zero for it. The first column should contain the coefficients of the highest-order and the second column should contain the coefficients of the next-highest order. If the leading coefficient in the first column is zero, replace it with a small nonzero value ε. The first two rows of the table are used to compute the remaining rows. The values in the remaining rows are computed as follows: Each element in a given row is computed by taking the determinant of the 2×2 submatrix formed by the two coefficients in the column to the left of the element and the two coefficients in the row above the element, divided by the value in the first column of the row directly above the element.
If any of the elements in a row are zero or have a zero divisor in the first column, the remaining elements in that row and all rows below it are also zero. If all of the elements in the first column are either positive or negative, the system is stable. If there are any sign changes in the first column, the number of sign changes is equal to the number of poles of the system in the right half of the s-plane. If there are any poles in the right half of the s-plane, the system is unstable. If there are any sign changes in the first column, but no poles in the right half of the s-plane, the system is marginally stable. Routh-Hurwitz tableFor the given closed-loop transfer function of a negative unity feedback system T(s) = S³ + 1/ 254 + s² + 2s, the Routh-Hurwitz table is given below:
Routh-Hurwitz TableS³ 1S² 2.54 2S¹ 1.29S⁰ 2For the stability of the given system, we need to check whether the number of sign changes in the first column is zero or not. As there are two sign changes in the first column of the Routh-Hurwitz table, this system is unstable. Hence, the given system is unstable, and its stability is not guaranteed.

Consider an airplane with a parasite drag coefficient of 0.02 when its landing gear is retracted, and 0.025 when it is deployed. Assume that the other drag polar parameter K does not change. The airplane is deigned to cruise for minimum thrust requirement with its landing gear retracted at certain altitude. Determine the % increase or decrease in the minimum thrust required if the airplane executes the same flight with its landing gear deployed (as may happen if its retraction mechanism fails).
please dont copy and paste answers from others don't answer in power i will have to report you.
The % increase or decrease in the minimum thrust required when the airplane executes the same flight with its landing gear deployed is 25% greater than with its landing gear retracted.
Parasite drag is the drag caused by the airplane's exposed parts such as engine, fuselage, and wings, among others. K is a constant that is a function of wing geometry, air density, and velocity of air; and it provides an overall measure of the airplane's lift and drag characteristics.The drag of an airplane is a function of its speed, altitude, and configuration, among other factors. The drag coefficient is a dimensionless factor that varies depending on the airplane's configuration. The drag polar equation is an expression of the drag coefficient as a function of K. Therefore, the drag polar curve is a plot of the drag coefficient as a function of K, and it describes the airplane's drag characteristics for various flight conditions.
Let D be the total drag force acting on the airplane, and T be the thrust force provided by the engines. The net force acting on the airplane is the difference between the thrust force and the drag force, i.e., F = T - D. If the airplane is in level flight, then F = 0, and T = D. Therefore, the minimum thrust required is the same as the total drag force, which can be expressed as follows:D = 1/2 * rho * V^2 * S * CDwhere rho is the air density, V is the true airspeed, S is the wing area, and CD is the drag coefficient. From the drag polar equation, CD can be expressed as:CD = CD0 + K * CL^2where CD0 is the parasite drag coefficient, K is a constant that depends on the wing geometry, air density, and velocity of air, and CL is the lift coefficient.

To replace malloc with mmap in the create and insertStart functions, you would need to use the mmap system call to allocate memory from the operating system instead of using malloc.
The mmap system call in C is used to map a file or device into memory. It allows us to allocate memory directly from the operating system instead of using malloc, which is a standard library function. To replace malloc with mmap in the create and insertStart functions, you would need to make the following modifications: In the create function: Instead of using malloc to allocate memory for the LinkedList structure, you would use the mmap system call to allocate memory directly from the operating system. The mmap call would return a pointer to the allocated memory block, which you would then assign to the list variable. In the insertStart function: Similarly, instead of using malloc to allocate memory for the Node structure, you would use the mmap system call to allocate memory. The mmap call would return a pointer to the allocated memory block, which you would assign to the n variable. It's important to note that using mmap requires additional considerations, such as specifying the file descriptor and size parameters correctly, as well as handling error conditions. Additionally, when using mmap, you need to explicitly manage the memory deallocation using the munmap system call when you no longer need the allocated memory.

3. Write a function named isUpperCase that takes a string argument and returns True if all the English letters in the argument string are upper case letters; otherwise it returns False. Example isUppe
The function isUpperCase(str) checks if all letters in the input string are uppercase. It returns True if so, False otherwise.To solve this problem, we can iterate through each character in the input string and check if it is an English letter and if it is uppercase.
If we encounter any lowercase letter or non-alphabetic character, we can immediately return False. If we successfully iterate through the entire string without encountering any lowercase letters or non-alphabetic characters, we return True. Here's the Python code for the isUpperCase function: def isUpperCase(s): for char in s: if char.isalpha() and not char.isupper(): return False return True In the code, we use the isalpha() method to check if the character is an English letter, and isupper() method to check if it is an uppercase letter. If the character fails these checks, we return False immediately. If we complete the loop without returning False, it means all the letters in the string are uppercase, so we return True. Here are a few examples of using the isUpperCase function: The first example returns True because all the letters in the string "HELLO" are uppercase. The second example returns False because the letter 'H' is uppercase, but 'e', 'l', and 'o' are lowercase. The third example returns True because there are no English letters in the string, so it satisfies the condition of having all uppercase letters.

Given that a machine twists a pair of copper wires at 5-rev/ft and runs at a speed of 300-ft/min, and the twisted pair is wounded by a mechanism supported by a deep-groove ball bearing with a catalog-rated life of 3,000-hr and a catalog-rated speed of 500-rpm, we want to find the time required to replace the bearing based on the machine hours.To solve this problem, we will need to do some unit conversions from the given values before we proceed with the calculations.We are given that the machine twists a pair of copper wires at 5-rev/ft and runs at a speed of 300-ft/min. We need to convert revolutions per foot to radians per foot.
The mass of the twisted pair of copper wires is given by:m = πr2lρwhere r is the radius of the twisted pair of copper wires, l is the length of the twisted pair of copper wires, and ρ is the density of copper.

There is a Mealy state machine with a synchronous input signal A and output signal X. It is known that two D flip-flops are used, with the following excitation and output equations:
Do = A + Q₁Q
D₁ = AQo
X = AQ1Q
Assume that the initial state of the machine is Q₁0 = 00. What is the output sequence if the input sequence is 000110110?
The output sequence if the input sequence is 000110110 is 000000010. The state transition table for the Mealy state machine is shown below: Input: A / Current State: Q1 Q0 / Next State: Q1' Q0' / Output: X0 / (initial state) 0 0 / 0 0 / 0 0 / 0 0 / 0 1 / 0 1 / 0 0 / 0 1 / 1 0 / 1 0 / 0 1 / 1 1 / 1 0 / 1 1 / 1 1 / 0 0
To determine the output sequence, we need to perform the following steps:
Step 1: Begin in the initial state Q1Q0 = 00 and input A = 0.
Step 2: Use the state transition table to find the next state Q1'Q0' and the output X0. Q1Q0 = 00 and A = 0 → Q1'Q0' = 00 and X0 = 0.
Step 3: Use the excitation and output equations to find the inputs to the D flip-flops. For the first flip-flop, Do = A + Q1Q0 = 0 + 0*2^1 + 0*2^0 = 0 and Q1' = 0. For the second flip-flop, D1 = AQ0 = 0*0 = 0 and Q0' = 0. The inputs to the D flip-flops are Do = 0 and D1 = 0.
Step 4: Clock the flip-flops and update the current state Q1Q0. Q1Q0 = 00 → flip-flops clocked → Q1Q0 = Q1'Q0' = 00.
Step 5: Repeat steps 2-4 for the remaining input sequence. The output sequence is the concatenation of the X0 values found in step 2. The complete process is shown in the table below:
Input A / Current State Q1Q0 / Next State Q1'Q0' / Output X0 / D flip-flop inputs Do D1 / New state Q1Q0 / Clock flip-flops / Output sequence X000 / 00 / 00 / 0 0 / 00 / ✓ / 000001 / 00 / 01 / 0 0 / 01 / ✓ / 000011 / 01 / 11 / 0 0 / 11 / ✓ / 000110 / 11 / 10 / 0 0 / 10 / ✓ / 000101 / 10 / 01 / 0 0 / 01 / ✓ / 000111 / 01 / 11 / 1 0 / 11 / ✓ / 000110 / 11 / 10 / 0 1 / 10 / ✓ / 000010 / 10 / 00 / 0 0 / 00 / ✓ / 0001

The input impedance of the CE is much lower than that of a CB while operating under the same conditions. Select one O True Ofalse A common emitter amplifier is non-inverting The output is always in phase with the input. Select one Ofrue OFalie
The answer to the first question is False. The input impedance of a CE amplifier is higher than that of a CB amplifier. This is because the input signal is applied to the base of the transistor in a CE amplifier, while it is applied to the emitter in a CB amplifier. The base of a transistor has a much higher impedance than the emitter, so the input impedance of a CE amplifier is correspondingly higher.
The statements are as follows:
1. The input impedance of the CE (Common Emitter) is much lower than that of a CB (Common Base) while operating under the same conditions.
Answer: True
In a common emitter configuration, the input impedance is relatively low compared to the common base configuration. The common emitter amplifier has a lower input impedance due to the biasing and input coupling arrangements, which typically involve a resistor in series with the base terminal.
2. A common emitter amplifier is non-inverting.
Answer: False
A common emitter amplifier is an inverting amplifier. The output signal is phase-reversed compared to the input signal. When the input voltage increases, the output voltage decreases, and vice versa.
3. The output of a common emitter amplifier is always in phase with the input.
Answer: False
The output of a common emitter amplifier is phase-reversed compared to the input. This means that when the input signal goes positive, the output signal goes negative, and vice versa. Therefore, the output of a common emitter amplifier is 180 degrees out of phase with the input signal.

A controller operates in an integral mode within the range of 9 to 14 Pa. The output controller was reported 22% at the initial stage with the parameter K, = -0.15 s¹ under the constant error input, ep. After 2 s of filling up of the water, the controller outputs 31%. By adhering to the set point of the pressure 12 Pa, calculate the new measured pressure.
The new measured pressure will be 2.56 Pa is the answer.
Given that the controller operates in an integral mode within the range of 9 to 14 Pa. The output controller was reported 22% at the initial stage with the parameter K, = -0.15 s¹ under the constant error input, ep. After 2 s of filling up the water, the controller outputs 31%. By adhering to the set point of the pressure of 12 Pa, we need to calculate the newly measured pressure.
As per the question, the controller operates in an integral mode. So, it can be represented as, Output = Kp (Ep + (1/Ti) ∫(Ep dt) + Td (dEp/dt)) Where Kp = Proportional gain Ti = Integral time constant Td = Derivative time constant Ep = Error at any instant of time= Setpoint - Process Variable
In the given problem, we know that, Kp = -0.15 s^-1ep = 12 - x (New measured pressure)x1 = 22% (Initial) = 0.22x2 = 31% = 0.31t = 2 s
So, the error at the initial stage, ep1 = 12 - x1 = 12 - (9 + 0.22(14 - 9)) = 10.04 Pa
The error after 2 seconds, ep2 = 12 - x2 = 12 - (9 + 0.31(14 - 9)) = 9.35 Pa
From the given data, we have, Kp (Ep + (1/Ti) ∫(Ep dt) = Output2 - Output1= 0.31 - 0.22 = 0.09
solving for the integral term,∫(Ep dt) = (Output2 - Output1) * Ti/Kp∫(Ep dt) = (0.31 - 0.22) * (-1.0/0.15) = -0.6s
Now, solving for new measured pressure,x = 12 - Ep2= 12 - (Ep1 + ∫(Ep dt))= 12 - (10.04 - 0.6)= 2.56 Pa
Therefore, the new measured pressure will be 2.56 Pa.
