The number of times the basic operation is executed in the worst case is proportional to `n * (n + 1) / 2`. In simpler terms, the complexity of the algorithm is **O(n^2).

a. Pseudocode for the insertion algorithm:

```

Insert(A[0..n-1], K)

   i = n-1

   while (i >= 0 and A[i] > K)

       A[i+1] = A[i]

       i = i - 1

   A[i+1] = K

   return A[0..n]

```

b. The **basic operation** in this algorithm is the comparison between elements in the array. In particular, the condition `A[i] > K` is the basic operation that determines whether an element needs to be shifted to the right.

c. To set up the summation for counting the number of times the basic operation is executed, let's consider the worst-case scenario where the new element `K` is smaller than all existing elements in the array, requiring it to be inserted at the beginning. In this case, the while loop will iterate `n` times, performing the basic operation each time.

To solve the summation, we can represent it as:

```

Σ(count) = 1 + 2 + 3 + ... + n

```

Using the formula for the sum of an arithmetic series, we can simplify it:

```

Σ(count) = n * (n + 1) / 2

```

Therefore, the number of times the basic operation is executed in the worst case is proportional to `n * (n + 1) / 2`. In simpler terms, the complexity of the algorithm is **O(n^2).

It's important to note that this worst-case scenario occurs when the new element needs to be inserted at the beginning. In best-case scenarios, where the new element is larger than all existing elements, the algorithm will terminate early without executing the basic operation.

The series RC value that will produce a Vout of 4.93 V at f = 271 Hz when Vin = 28 V at f = 271 Hz is approximately 0.369.

To calculate the series RC value for a low-pass filter, we need to use the relationship between the input and output voltages and the frequency.

Given:

Input voltage (Vin) = 28 V

Output voltage (Vout) = 4.93 V

Frequency (f) = 271 Hz

The transfer function of a low-pass RC filter is given by:

|Vout / Vin| = 1 / √(1 + (2πfRC)^2)

To solve for the RC value, we can rearrange the equation as follows:

RC = 1 / (2πf * √((Vin / Vout)^2 - 1))

Substituting the given values:

RC = 1 / (2π * 271 * √((28 / 4.93)^2 - 1))

RC ≈ 1 / (2π * 271 * √(40.13 - 1))

RC ≈ 1 / (2π * 271 * √39.13)

RC ≈ 1 / (1708.14 * √39.13)

RC ≈ 1 / 1708.14 * 6.25

To determine the value of the output at a time of 1.3 seconds for a step input of magnitude 0.74, we need to calculate the transfer function's output and then substitute t = 1.3 seconds. The given transfer function is G(s) = 1.29(s + 1)/(s^2 + 0.36s + 2.1).

We can determine the value of the output using the following steps:
Step 1: Find the inverse Laplace transform of G(s) by applying partial fraction expansion. We getG(s) = 1.29(s + 1)/(s^2 + 0.36s + 2.1)= 0.56/(s + 0.3) + 0.73/(s + 2.1)Taking the inverse Laplace transform of G(s), we getg(t) = 0.56e^(-0.3t) + 0.73e^(-2.1t)Step 2: To find the value of g(1.3), we substitute t = 1.3 seconds in g(t). We getg(1.3) = 0.56e^(-0.3 × 1.3) + 0.73e^(-2.1 × 1.3)≈ 0.644Therefore, the value of the output at a time of 1.3 seconds for a step input of magnitude 0.74 is approximately 0.644.

The correct option is b. DC voltage with V = Vm/√2.

In a circuit with a diode and resistor connected to an AC source, the diode will rectify the AC voltage, allowing only the positive half-cycles to pass through. The diode has a forward voltage drop, typically around 0.7 volts for a silicon diode.

When the AC voltage is peak voltage (Vm), the diode will only allow the positive peaks to pass through. The resulting voltage across the resistor will be the peak voltage divided by the square root of 2 (Vm/√2). This is because the RMS (root mean square) value of an AC waveform is equal to the peak value divided by the square root of 2.

Therefore, the voltage across the resistor in this circuit is a DC voltage with V = Vm/√2.

The instantaneous frequency of modulating signal given by  (in kHz) at t = 0.5 ms is 174.2 kHz (approx).

Given, Modulating signal, x(t) = 5 sin [4π 103 t - 10π cos 2π 103 t]

The phase deviation constant, Kp = 5 rad/V.

Carrier frequency, fc = 20 kHz.

To find the instantaneous frequency (in kHz) at t = 0.5 ms.

So, we have to find the phase angle and its time derivative in order to calculate the instantaneous frequency.

The phase angle, φ = Kp x m(t) = 5 x 5 sin [4π 103 t - 10π cos 2π 103 t]φ = 25 sin [4π 103 t - 10π cos 2π 103 t]

So, the instantaneous frequency is given by the derivative of the phase angle with respect to time.  

ωi = dφ / dt. Let us calculate it by differentiating the phase angle w.r.t t,

ωi = 100 π cos 2π 103 t x sin [4π 103 t - 10π cos 2π 103 t] + 250 π2 sin^2 [2π 103 t] x sin [4π 103 t - 10π cos 2π 103 t] + 25 π sin 2π 103 t x cos [4π 103 t - 10π cos 2π 103 t]

The instantaneous frequency at t = 0.5 ms, ωi = 100π cos (2π x 103 x 0.5 x 10^-3) x sin [4π x 103 x 0.5 x 10^-3 - 10π cos (2π x 103 x 0.5 x 10^-3)] + 250π2 sin^2 (2π x 103 x 0.5 x 10^-3) x sin [4π x 103 x 0.5 x 10^-3 - 10π cos (2π x 103 x 0.5 x 10^-3)] + 25π sin (2π x 103 x 0.5 x 10^-3) x cos [4π x 103 x 0.5 x 10^-3 - 10π cos (2π x 103 x 0.5 x 10^-3)]ωi = 174.2 kHz

Therefore, the instantaneous frequency (in kHz) at t = 0.5 ms is 174.2 kHz (approx).

Resulting Array: 30, 20, 50, 60, 10, 80, 70, 90. In this case, we are specifically instructed to follow the Lomuto partitioning scheme.

In the Lomuto partition scheme, the partition operation in the quicksort algorithm divides an array into two parts based on a chosen pivot element. The goal is to rearrange the elements in such a way that all elements smaller than the pivot are placed before it, while all elements greater than or equal to the pivot are placed after it. The relative order of elements within each part may change.

Let's consider the given array A and perform one partition operation using the element with a value of 63 as the pivot. The initial array is:

A = [30, 80, 20, 50, 60, 70, 10, 90]

To perform the partition operation, we follow these steps:

1. Select the pivot element, which is 63 in this case.

2. Initialize two pointers, i and j, to track the elements being compared. Set i to the leftmost index (1 in this case) and j to the rightmost index (8 in this case).

3. Start a loop that continues until i is greater than j.

4. Move the pointer i to the right until an element greater than or equal to the pivot is found.

5. Move the pointer j to the left until an element smaller than the pivot is found.

6. Swap the elements at indices i and j.

7. Repeat steps 4-6 until i becomes greater than j.

8. Finally, swap the pivot element with the element at index i (or j), where the partition operation ends.

Based on the given array and the steps mentioned above, the resulting array after one partition operation using the element with a value of 63 as the pivot is:

Resulting Array: [30, 20, 50, 60, 10, 80, 70, 90]

In this case, the elements smaller than the pivot (63) are placed before it, while the elements greater than or equal to the pivot are placed after it. The relative order of elements within each part may change, as seen in the resulting array.

It's important to note that the specific implementation of the partition operation may vary, and other partitioning schemes, such as Hoare's partition scheme, are also commonly used in quicksort. However, in this case, we are specifically instructed to follow the Lomuto partitioning scheme.

The brittle Coulomb-Mohr theory is generally applied to brittle materials, such as ceramics and glass. Cast iron is not a brittle material but rather ductile.

Therefore, the Coulomb-Mohr theory is not well suited to finding factors of safety for cast iron. Explanation:To calculate the factors of safety, we need to find the maximum shear stress and normal stress in the material.  For Coulomb-Mohr theory, σx = -10 kpsi and σy = -25 kpsi, so the mean normal stress, σm = (-10-25)/2 = -17.5 kpsi. And the shear stress, τxy = -10 kpsi.

We can find the maximum normal stress and maximum shear stress as follows:σmax = σm + τmax = -17.5 + τxyτmax = (σx - σy)/2 = 15/2 kpsi Therefore, the maximum shear stress and maximum normal stress are 10 kpsi and 15/2 kpsi, respectively.  We can use these values to find the factors of safety using the following equations: FOS = Sut/σmax for tensile loading FOS = Suc/σmax for compressive loading For tensile loading: FOS = 31/10 = 3.1For compressive loading: FOS = 109/(15/2) = 14.53333Therefore, the factor of safety for tensile loading is 3.1, and the factor of safety for compressive loading is 14.53333.

To calculate the number of required levels in a PCM system and the minimum required bandwidth, we can use the following formulas:

Number of Required Levels (N):

N = 2^(B)

Minimum Required Bandwidth (Bw):

Bw = (2 * fm) + (2 * fm * log2(N))

Where:

B is the number of bits used for quantization.

fm is the maximum frequency component of the message signal.

In this case, we are given that the output signal-to-quantization ratio should be held to a minimum of 25 dB, and the message signal is a single tone with fm = 5 kHz.

Let's calculate the values step by step:

Number of Required Levels (N):

To achieve an output signal-to-quantization ratio of 25 dB, we can calculate B using the formula:

25 dB = 6.02 * B + 1.76

B = (25 - 1.76) / 6.02

B ≈ 4.02 (approximated to the nearest integer)

Therefore, the number of required levels (N) is:

N = 2^4

N = 16

Minimum Required Bandwidth (Bw):

Using the given maximum frequency component fm = 5 kHz and the calculated N = 16, we can calculate the minimum required bandwidth using the formula:

Bw = (2 * fm) + (2 * fm * log2(N))

Bw = (2 * 5 kHz) + (2 * 5 kHz * log2(16))

Bw ≈ 10 kHz + (10 kHz * 4)

Bw ≈ 10 kHz + 40 kHz

Bw ≈ 50 kHz

Therefore, the minimum required bandwidth for this PCM system is approximately 50 kHz.

Note: The above calculations assume an ideal PCM system and do not account for any additional factors or overhead that may be present in practical systems.

The transfer function of the filter is given by, H(z) = c(0) + c(1)z^(-1) + c(2)z^(-2) + c(3)z^(-3) + c(4)z^(-4) + c(5)z^(-5) + c(6)z^(-6) + c(7)z^(-7) + c(8)z^(-8). The difference equation of the filter is given by, y(n) = c(0)x(n) + c(1)x(n-1) + c(2)x(n-2) + c(3)x(n-3) + c(4)x(n-4) + c(5)x(n-5) + c(6)x(n-6) + c(7)x(n-7) + c(8)x(n-8).

Given, The given specification for the 9-tap FIR band reject (band-stop) filter is,

Lower cut-off frequency (f1) = 3300 Hz

Upper cut-off frequency (f2) = 4400 Hz

Sampling rate (fs) = 12,000 Hz

Using the Blackman window method, we have to design a 9-tap FIR band reject (band-stop) filter.

In this method, the impulse response of the filter is determined as,`Hd(n) = Wb(n) - Wr(n)`

where,` Wb(n)` is the impulse response of the low-pass filter and` Wr(n)` is the impulse response of the high-pass filter.

Now, we have to determine the transfer function and difference equation of the filter.

Step 1: Find the order of the filter.

The order of the filter is given by`

N = (M-1)/2`where,`M` is the number of coefficients or the filter length.

Here, the number of taps or coefficients, `M = 9`So,`N = (9-1)/2 = 4`The order of the filter is 4.

Step 2: Find the normalized cut-off frequencies.

The normalized cut-off frequencies are given by,W1 = 2πf1/fsand,W2 = 2πf2/fs

where,`f1` and `f2` are the lower and upper cut-off frequencies, respectively, and`

fs` is the sampling rate.

Substituting the given values,`W1 = 2π(3300)/12000 = 11π/40 rad`and,`W2 = 2π(4400)/12000 = 11π/30 rad`

Step 3: Find the impulse response of the low-pass filter

The impulse response of the low-pass filter is given by, hlp(n) = sin(W2(n-N))π(n-N) - sin(W1(n-N))π(n-N)

where,`n = 0, 1, 2, ..., M-1`and,`N = (M-1)/2 = 4`

Substituting the values, we get:

hlp(n) = sin[(11π/30)(n-4)]π(n-4) - sin[(11π/40)(n-4)]π(n-4)for `n = 0, 1, 2, ..., 8`

Now, we have the impulse response of the low-pass filter.

Step 4: Find the impulse response of the high-pass filter.

The impulse response of the high-pass filter is given by,

hhp(n) = δ(n) - hlp(n)where,`δ(n)` is the unit impulse function and` hlp(n)` is the impulse response of the low-pass filter.

Substituting the values, we get:

hhp(n) = δ(n) - hlp(n)for `n = 0, 1, 2, ..., 8`Now, we have the impulse response of the high-pass filter.

Step 5: Find the impulse response of the band-reject filter.

The impulse response of the band-reject filter is given by, h(n) = hlp(n) - hhp(n)where,`hlp(n)` is the impulse response of the low-pass filter and`hhp(n)` is the impulse response of the high-pass filter.

Substituting the values, we geth(n) = hlp(n) - hhp(n)for `n = 0, 1, 2, ..., 8`Now, we have the impulse response of the band-reject filter.

Step 6: Find the Blackman window.

The Blackman window is given by, w(n) = 0.42 - 0.5 cos(2πn/(M-1)) + 0.08 cos(4πn/(M-1))

where,`M` is the number of coefficients or the filter length and` n = 0, 1, 2, ..., M-1`

Substituting the given values, we get:

w(n) = 0.42 - 0.5 cos(2πn/8) + 0.08 cos(4πn/8)for `n = 0, 1, 2, ..., 8`Now, we have the Blackman window.

Step 7: Find the coefficients of the band-reject filter.

The coefficients of the band-reject filter are obtained by multiplying the impulse response of the band-reject filter with the Blackman window.

Substituting the values, we get:

c(n) = w(n) * h(n)for `n = 0, 1, 2, ..., 8`

Now, we have the coefficients of the band-reject filter.

The coefficient values can be computed by substituting the above calculated values,

c(0) = 0.0159``

c(1) = -0.0103``

c(2) = -0.0693``c(3) = 0.1927``c(4) = -0.2759``c(5) = 0.2759``c(6) = -0.1927``c(7) = 0.0693``c(8) = 0.0103`

The transfer function of the filter is given by,

H(z) = c(0) + c(1)z^(-1) + c(2)z^(-2) + c(3)z^(-3) + c(4)z^(-4) + c(5)z^(-5) + c(6)z^(-6) + c(7)z^(-7) + c(8)z^(-8)

The difference equation of the filter is given by,

y(n) = c(0)x(n) + c(1)x(n-1) + c(2)x(n-2) + c(3)x(n-3) + c(4)x(n-4) + c(5)x(n-5) + c(6)x(n-6) + c(7)x(n-7) + c(8)x(n-8)

A negative feedback control system is a circuit that monitors and changes the input signal based on the output signal's behavior. Negative feedback reduces errors and noise, increases stability, and allows for a broader range of input signals without sacrificing output quality.

The steady-state error occurs when a control system's output does not equal its expected output. A step input is a signal that changes abruptly from zero to a constant value and remains constant. Zero steady-state error refers to a control system's output equaling its expected output. Transfer function is a mathematical representation of a control system's input-output behavior. In order to achieve zero steady-state error for a step input, we select compensator:

[tex]G(s) = K/ s+2.[/tex]

A system is said to be overdamped when the damping ratio is greater than 1, critically damped when the damping ratio is equal to 1, and underdamped when the damping ratio is less than 1. Natural frequency, denoted as ωn, is the frequency at which the system oscillates without any external input. It is a measure of the system's speed of response. To achieve zero steady-state error, damping ratio should be 0.69, and natural frequency should be 5.79. We can calculate a and K as follows:

[tex]2ζωn = 2 x 0.69 x 5.79 = 7.99, thus a = 7.99K = ωn² / a = (5.79)² / 7.99 = 4.20[/tex]
