2.Describe the parallel operating conditions in transformers in detail. Give the tolerances of the conditions. Why does circulation flow occur? Calculate the load sharing statement for transformers connected in parallel.

Compare and contrast the Ziegler-Nichols and the Pessen tuning methods. Explain their advantages and drawbacks.

2. Design a digital circuit, using a decoder, only Nor gates, a 7-segment display, and D Flip Flops, that repeatedly outputs the sequences of characters ‘P’, ‘E’, ‘A’, ‘L’ if x=0 and ‘L’, ‘E’, ‘A’, ‘P’ if x=1 .

Topic 6. One transistor amplifier (BJT)

1. Design a single transistor amplifier (BJT) with appropriate coupling and bypassing capacitors. You can use the examples from the book or homework, but need to change the parameters values .

2. Draw the DC equivalent circuit and find the Q point. Draw the AC equivalent circuit and find parameters of your full amplifier circuit (gain and input resistance) .

3. Simulate the FULL amplifier circuit in DC state (you cannot use DC operating point analysis), find and indicate the Q point on the circuit diagram and compare with theoretical results.

4. Simulate the FULL amplifier circuit using appropriate sin input signal(s). Show the graphs of all voltages and currents needed to calculate amplifier parameters. Using the simulation results from the graph, find the same amplifier circuit parameters, and compare with theoretical result. Draw your conclusions.

Please show parameters and all graphs :D

Thanks

For each of the following difference equations

(i) y[n + 1] + 1.5y[n] = x[n]

(ii) y[n + 1] + 0.8y[n] = x[n]

(iii) y[n + 1] - 0.8y[n] = x[n]

For the difference equations given in Problem 2.16:

(a) Find a closed-form solution for y[n] when x[ n] = 0 for all n and y[0] 2.

(b) Find a closed-form solution for y[n] when x[n] = u[n] and y[ 0] = 0.

(c) Find a closed-form solution for y[n] when x[n] = u[n] and y[0] = 2.

Why do eigenvalues stay the same from one state space model to another state space model while eigenvectors change when the state space model changes? Please explain in depth details!!

a)A small conducting ring is placed inside a solenoid and is concentric with the axis of the solenoid. If the current in the solenoid changes direction, explain what happens to the magnetic flux through the ring.

b)Explain how a uniform magnetic field (one constant in magnitude and direction) can be created.

How can we control the speed of Synchronous an AC Generator and give me a picture of Synchronous an AC Generator regarding of what you are planning to say about controlling the speed? Give me details as much as you can.
