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.

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.

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)

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

The greedy algorithm works on the principle of making the locally optimal choice at each stage with the hope of arriving at a globally optimal solution. Let's consider the least coin-changing problem to demonstrate the two properties of the greedy algorithm.

1. Optimal substructure PropertyThe optimal substructure property is the principle that a globally optimal solution can be obtained by combining locally optimal solutions. The least coin-changing problem has this property. Let's say we have a set of coins of different denominations, and we want to give change for a certain amount. We can obtain the minimum number of coins required to give change by choosing the largest denomination that is less than the amount left to be changed.

We can repeat this process for the remainder of the change until we obtain the minimum number of coins required. For example, if we have coins of denominations 1, 2, and 5, and we want to give change for 10, we can choose the coin of denomination 5 first and then 2 coins of denomination 2. This approach can be generalized for larger denominations and amounts.

2. Greedy-choice propertyThis property states that a locally optimal choice made at a certain stage should not affect the final outcome of the algorithm. For the least coin-changing problem, the greedy-choice property can be demonstrated as follows.

Let's say we have coins of denominations 1, 3, and 4, and we want to give change for 6. If we choose the coin of denomination 4 first, we are left with 2, which requires 2 coins of denomination 1 to obtain the minimum number of coins required. However, if we choose the coin of denomination 3 first, we are left with 3, which requires only 1 coin of denomination 3 to obtain the minimum number of coins required.

To design a system that converts a 7 MHz LSSB (Lower Sideband Suppressed) signal to a 50 MHz USSB (Upper Sideband Suppressed) one, several stages are involved. Here is a general approach for the system design, along with the justification and sketching of output spectra for each stage:

1. **Stage 1: Upconversion**  

In this stage, the 7 MHz LSSB signal needs to be upconverted to a higher frequency to reach the desired 50 MHz USSB frequency range. This can be achieved using a mixer or a frequency multiplier. By combining the 7 MHz LSSB signal with a local oscillator frequency of 43 MHz (50 MHz - 7 MHz), the desired upconversion can be achieved. The output spectrum of this stage will show the upconverted signal centered around 50 MHz.

2. **Stage 2: Sideband Suppression**  

Since the target signal is USSB, the lower sideband needs to be suppressed. This can be achieved using a bandpass filter centered at 50 MHz, which allows only the upper sideband to pass while attenuating the lower sideband significantly. The output spectrum at this stage will show the upper sideband dominant and the lower sideband suppressed.

3. **Stage 3: Post-filtering and Amplification**  

In this stage, further filtering may be required to eliminate any unwanted spurious components or harmonics introduced during the previous stages. Additionally, amplification may be applied to ensure the desired signal strength is achieved. The output spectrum at this stage will reflect the filtered and amplified USSB signal centered at 50 MHz.

By following this system design, the output spectra can be sketched for each stage to visualize the signal transformation and justify the design choices. The sketches would depict the frequency domain representation of the signals at each stage, highlighting the relevant frequency components and the desired signal characteristics.

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

RC ≈ 0.000369

Multiplying by 1000 (as stated in the notes), we get:

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]

Therefore, the compensator transfer function is [tex]G(s) = 4.20 / (s + 2)[/tex]

Stator reactance, X1 = 0.82 Ω/phase

Rotor resistance, R2' = 0.1312 Ω/phase

Rotor reactance, X2 = 0.812 Ω/phase

1. The synchronous speed of the machine is given by the formula, ns = (120 × f)/p= (120 × 60)/8= 900 rpm

2. The slip of the machine is given by the formula, s = (ns - n)/ns Where n is the actual speed of the rotor. The prime mover is running at 1000 rpm, so the slip is:
