Answers

Answer 1

a. Schematic diagram of the circuit:

The schematic diagram of the given sequential circuit with two JK flip-flops A and B and one input x is as shown below:

b. State equations A(t+1) & B(t+1)

The JK flip-flop is used to create a state equation.

As a result, we must first produce K and J equations.

K_A = A' . x + A .

B_J_A = A . x + A' .

BJ_B = A . B' + A' .

B'J_B = A . B + A' .

B' = K_B' + J_B'

Using these equations, the state equations for A(t+1) and B(t+1) can be obtained.

A(t+1) = J_A' . A(t) + K_A' . A'(t)

B(t+1) = J_B' . B(t) + K_B . B'(t)

Thus, the state equations for A(t+1) and B(t+1) are:

A(t+1) = A(t) . x' + A'(t) . (A . x + A' . B)

B(t+1) = B(t) . (A . B' + A' . B') + B'(t) . (A . B + A' . B')

c. State table of the circuit:

The state table of the given sequential circuit with two JK flip-flops A and B and one input x is as shown below:

The state diagram of the given sequential circuit with two JK flip-flops A and B and one input x is as shown below:e.

State transitions based on the input sequence (011001110101) & initial state (a=00):

The initial state is a = 00.

d. 2165A

Answers

The inrush current on a 12470-277/480V 150kVA delta-wye transformer assuming the inrush is 12X full load amps for 6 cycles is 2165A.

So, the correct option is d. 2165A.

What is inrush current?

Inrush current is an electric current that flows through electrical circuits when they're first energized.

Inrush current is caused by the rapid charging of the inherent capacitance of the load and transformer windings when they are first energized.

The inrush current for a transformer is typically 12 times greater than the full-load current.

The formula to calculate inrush current is:

I(inrush) = X(Full load amps)

Here, X = 12 for a 6 cycle inrush.

Hence the formula becomes:

I(inrush) = 12 × Full load amps

For the given transformer,

Full load amps = kVA ÷ (√3 × Volts)

Full load amps = 150000 ÷ (√3 × 480)

Full load amps = 180.99 amps

Therefore, the inrush current will beI(inrush) = 12 × 180.99I(inrush)

= 2171.88 amps,

which is approximately equal to 2165A.

Apply the lowpass to highpass transformation to the cascade form of H(s) in (c) to obtain a highpass transfer function. For this case assume that the cutoff frequency of the filter is wc.

Answers

The highpass transfer function, H_hp(s) is given by Eq. (5).

To apply the lowpass to highpass transformation to the cascade form of H(s) in (c) to obtain a highpass transfer function, the following steps should be followed:

Step 1: Replace s in H(s) by 1/s to get H(1/s).

Step 2: Determine the rational function H(-s) by replacing s with -s in H(s)

Step 3: Multiply the rational functions obtained in steps 1 and 2.

The product of the two rational functions obtained is the highpass transfer function, H_hp(s)

Here are the steps in details:

Step 1: Replace s in H(s) by 1/s to get H(1/s).H(s) = K (s + wc) / [(s + 1)(s + 2wc)(s + 3wc)]  ... Eq. (1)H(1/s) = K (1/wc + s) / [(1/s + 1)(1/s + 2wc)(1/s + 3wc)]  ... Eq. (2)

Step 2: Determine the rational function H(-s) by replacing s with -s in H(s).H(-s) = K (-s + wc) / [(-s + 1)(-s + 2wc)(-s + 3wc)] ... Eq. (3)

Step 3: Multiply the rational functions obtained in steps 1 and 2.

The product of the two rational functions obtained is the highpass transfer function, H_hp(s)H_hp(s) = H(-s) * H(1/s) = K (-s + wc) / [(-s + 1)(-s + 2wc)(-s + 3wc)] * K (1/wc + s) / [(1/s + 1)(1/s + 2wc)(1/s + 3wc)] ... Eq. (4)

Simplifying Eq. (4),H_hp(s) = K * (wc - s) / [(s - 1)(s - 2wc)(s - 3wc)] * (s + wc) / [(s + 1)(s + 2wc)(s + 3wc)]H_hp(s) = K * (wc - s) / [(s^2 - 4wc*s + 3wc^2)(s^2 + 4wc*s + 3wc^2)] ... Eq. (5)

NPN Transistor structure: VCC 18V RC 9K RE1 300ohm RE2 2.7K VBB & VEE OV VBE 0.7V. Voltmeter across RC is 6.075V.

This transistor has a beta of 150. Knowing beta and Ic (I came up with 3.325mA), find Ib.

Not sure how to do this. Can you please help?

Answers

To find Ib, divide the collector current (Ic) by the beta (β) of the transistor. Ib = Ic / β = 3.325mA / 150 = 22.17μA.To calculate Ib, we can use the relationship between the collector current (Ic) and the base current (Ib) of an NPN transistor.

The base current is related to the collector current by the transistor's beta (β) value. Given that Ic is 3.325mA and the beta (β) of the transistor is 150, we can use the formula Ib = Ic / β to find the base current. Substituting the given values, we have Ib = 3.325mA / 150 = 22.17μA. The base current is determined by dividing the collector current by the beta value. This is because the base current controls the transistor's amplification factor, and the beta value represents the ratio of collector current to base current. In this case, with an Ic of 3.325mA and a beta (β) of 150, the calculated base current (Ib) is 22.17μA. This base current will drive the required collector current through the transistor according to its amplification characteristics.

Suppose you need to ensure that no more than 2 instances of a certain class C exist at any time. Illustrate briefly how this design requirements can be addressed with a variant of the Singleton pattern, giving a specification in pseudo-code of the public operation getInstance(Int) that needs to be in C; assume that such operation receives as input an integer with value 1 or 2, meaning that the respectively first or the second instance of C is to be returned by said operation.

Answers

To ensure that no more than 2 instances of class C exist at any time, we can use a variant of the Singleton pattern where we maintain two private static instances of class C.

The public operation getInstance(Int) would take an integer parameter as input, specifying which instance (the first or second) is to be returned by the method.

Here's a possible implementation of such a design in pseudo-code:

class C {

  private static C instance1 = null;

  private static C instance2 = null;

  private static int count = 0;

  private C() { }

  public static synchronized C getInstance(int number) {

     if (number == 1) {

        if (instance1 == null) {

           instance1 = new C();

        }

        return instance1;

     } else if (number == 2) {

        if (instance2 == null) {

           instance2 = new C();

        }

        return instance2;

     } else {

        throw new IllegalArgumentException("Invalid instance number");

     }

  }

}

In this implementation, the constructor for C is made private to prevent external instantiation, and the getInstance(Int) method is made synchronized to ensure thread safety. The count variable keeps track of how many instances of the class have been created so far.

When getInstance(Int) is called with a valid instance number (1 or 2), it checks whether the corresponding instance has already been created. If not, it creates a new instance of C and returns it. If the maximum number of instances (2) has already been reached, calling getInstance(Int) with an invalid instance number will throw an exception indicating that the requested instance number is invalid.

18 11 points Save Arawer A synchronous generator is delivering 0.95 pu of active power and 0.3 pu reactive power to an infinite bus, with a voltage of V=1.0 pu, through transmission line. The generator has a direct-axis transient reactance X-0.2 pu and the line reactance is XL -0.4 pu. A temporary three-phase fault occurred on the sending end of the line. When the fault was cleared, the line remained connected. Calculate the followings:
a.Current flowing into the infinite bus 6. [2 Mark]
b.Transient internal voltage of the generator [2 Mark)
c.Maximum power transfer [2 Mark)
d.. Initial operating power angle
e.Critical clearing angle & of the system [3 Marks)

Answers

a. To calculate the current flowing into the infinite bus, we can use the power equation: \[ P = |V| \cdot |I| \cdot \cos(\theta) \]

Given:

Active power, P = 0.95 pu

Voltage magnitude at the bus, |V| = 1.0 pu

Since the power factor (cosine of power angle, θ) is not given, we'll assume a power factor of unity (θ = 0). Rearranging the equation, we can solve for the current magnitude, |I|:

\[ |I| = \frac{P}{|V| \cdot \cos(\theta)} \]

Substituting the given values, |I| = \(\frac{0.95}{1.0 \cdot 1.0}\) pu.

b. To calculate the transient internal voltage of the generator, we can use the equation:

\[ E_{\text{transient}} = |V| - jX \cdot |I| \]

Given:

X (direct-axis transient reactance) = -0.2 pu

|I| (current magnitude) = calculated in part (a)

Substituting the values, we can find the transient internal voltage, E_{\text{transient}}.

c. The maximum power transfer occurs when the load impedance matches the complex conjugate of the generator's internal impedance. In this case, the load impedance would be the transmission line's impedance. Since the line reactance is given as XL = -0.4 pu, we can assume the line's impedance as ZL = XL.

d. The initial operating power angle is not explicitly provided in the question. However, we can assume it to be zero (θ = 0) for simplicity.

e. The critical clearing angle (θcc) is the angle at which the fault must be cleared to prevent instability in the system. It can be calculated using the equation:

\[ \theta_{cc} = \arccos\left(\frac{|V|}{|E_{\text{transient}}|}\right) \]

Given:

|V| (bus voltage magnitude)

|E_{\text{transient}}| (transient internal voltage magnitude)

Substituting the values, we can calculate the critical clearing angle (θcc).

Please note that without specific numerical values for |V|, X, XL, and |E_{\text{transient}}|, it's not possible to provide precise numerical answers.

(a) What are its synchronous reactance and armature resistance in ohms?
(b) What is the magnitude of the intemal generated voltage E, at the rated conditions? What is its torque angle at these conditions?
(c) Ignoring losses, in this generator, what torque must be applied to its shaft by the prime mover at full load?

Answers

(a) To find the synchronous reactance and armature resistance in ohms, we need to convert the per-unit values to their corresponding actual values.

Given:

Per-unit synchronous reactance = 0.8

Per-unit armature resistance = 0.012

Base values:

Apparent power (Sbase) = 100 MVA

Voltage (Vbase) = 11.5 kV

To calculate the synchronous reactance in ohms:

Synchronous reactance (Xs) = Per-unit synchronous reactance * Xbase

Xbase = Vbase^2 / Sbase

Xs = 0.8 * (11.5 kV)^2 / 100 MVA

To calculate the armature resistance in ohms:

Armature resistance (Ra) = Per-unit armature resistance * Rbase

Rbase = Vbase^2 / Sbase

Ra = 0.012 * (11.5 kV)^2 / 100 MVA

(b) The magnitude of the internal generated voltage E at the rated conditions can be determined using the formula:

E = Vbase - (Ra + jXs) * I

where I is the rated current of the generator.

To find the torque angle at the rated conditions, we can use the power-angle equation:

tan(delta) = Xs / Ra

where delta is the torque angle.

(c) To determine the torque that must be applied to the generator shaft by the prime mover at full load, we can use the formula:

Torque = (Pout / (2 * pi * f)) / ((1 - s) * Ef)

where Pout is the output power at full load, f is the frequency, s is the slip, and Ef is the field voltage.

It's important to note that the slip (s) in a synchronous generator is zero because the rotor speed is synchronous with the stator frequency. Therefore, the torque required at full load would be zero since there is no slip-induced torque.

By calculating the above parameters, you can obtain the synchronous reactance and armature resistance in ohms, determine the magnitude of the internal generated voltage and torque angle at rated conditions, and understand that no additional torque is required at full load for a synchronous generator.

Timer0 of Atmega328p is configured to run in Phase Correct PWM mode. If OCROA register = (your roll number + 120), what will be the frequency and duty cycle of the generated signal on OCOA pin? Assume the system clock to be 8 MHz and Timero Prescalar to be 2. Timer configuration is such that OCOA is cleared on Compare Match when counting up and set when counting down.

Answers

In Atmega328p, Timer0 is a 8-bit timer. When we configure the Timer0 in the Phase Correct PWM mode, it means that the timer counts up to the maximum value (0xff) and then counts down to 0 before restarting again from 0.

This is known as Phase Correct PWM mode. Duty cycle of the PWM signal is the amount of time the signal is high compared to the total time period of the signal. Frequency of the PWM signal is the number of cycles of the PWM signal in a given time period. Now, let's calculate the frequency and duty cycle of the generated signal on OCOA pin. Given, OCROA register = (your roll number + 120)

= (xx + 120)OCROA

= (xx + 120)8 MHz

System Clock Timer Prescalar = 2When Timer0 is configured in Phase Correct PWM mode, the formula to calculate frequency and duty cycle of the PWM signal is: Fpwm = (Fclk / (N * 510))

The value of OCR0A is given as: OCR0A = (xx + 120) Now, substituting the given values in the formula, we get: Fpwm = (8 MHz / (2 * 510))

= 7.843 kHzDuty Cycle

= ((xx + 120) / 255) * 100

Let's assume the value of xx is 11.Duty Cycle = ((11 + 120) / 255) * 100

Duty Cycle = 53.33% Therefore, the frequency of the generated signal on OCOA pin is 7.843 kHz and the duty cycle of the generated signal is 53.33% when OCROA register is equal to (your roll number + 120) and the timer is configured in Phase Correct PWM mode.

This is because there is a single new line character appearing at the end of each line (including the last line).

For simplicity in our assumptions, the routers use a stop-and-wait protocol and each virtual circuit has one buffer dedicated to it for each direction of traffic. If it takes T sec to transmit a packet (data or acknowledgement) and there are n routers (or user nodes) on the path, what is the rate at which packets are delivered to the destination host? Assume that transmission errors are rare and that the host-router connection is infinitely fast?
