Write and verify a behavioral Verilog model of J-K flip-flop with active-low asynchronous reset.

Synchronous Counter
Design a counter with MOD-5 (0-3-4-1-6) and explain its operation.

One period of a real-time signal x(t) =2Sin(20*pi*t) , starting at t=0, has to be processed in a 4-bit digital computer. The A/D card have a sampling frequency of 55Hz and the input range is +/- 2Volts.

i) What are the values recorded in the sampled signal x[n] ?

ii)What is the resulting quantized signal?

iii)What is the resulting digitized/coded signal?

iv)If the sampled signal x[n] was filtered using a moving average filter of length 3 , what would the filtered signal be?

(6) In the presence of an applied electric field, the bandgap of a semiconductor effectively

(   )

(A) Increases with increasing electric field, and decreases with decreasing temperature

(B) Decreases with increasing electric field, and increases with decreasing temperature

(C) Decreases with increasing electric field, and decreases with decreasing temperature

(D) Increases with increasing electric field, and increases with decreasing temperature

Can you give me any information and equations/pictures you can for:

1.Op amp bandwidth limitations/ gain bandwidth product

2.negative feedback

3.closed loop gain

4.input bias current

I have a test tomorrow and those are the four things I forgot all about so please explain them and any information I may need on those topics.

Thank you

In this experiment you will use an online circuit board to build three circuits: a series circuit with three resistors, a parallel circuit with three resistors, and a circuit with a combination of parallel and series resistors. You will use an ammeter and a volt meter to measure the current flow and voltage across the resistors in the circuits. After you record the results of your experiment, you will be able to compare the measurements you take with what Ohm’s Law predicts. You will record the data in the Experiment Worksheet and answer questions as indicated in the experiment worksheet. Your answers should be presented in a report format.

Series Circuit Set Up

Place a battery from slide 1 in the upper middle portion of the blue work space. Place and connect a switch to the right of the battery. Place and connect an ammeter to the right of the switch (placing it in-line where we want to measure the amperage). The ammeter can be found in the second box on the right side. Moving vertically, place three (3) resistors from slide 1 in series. These will be referred to as R1, R2, and R3, respectively, from left to right. On the left side, place a wire connected to the left end of the battery and running to left and then downward, stretched to about the same height as the resistors on the right side. Place and stretch a wire running horizontally to connect the left wire and right resistors. Click on the first resistor (R1) and adjust the resistance to 4 Ω. Repeat for the other resistors. Click on the battery to ensure it is set to 10.0 V. Place a voltmeter across the first resistor and measure the voltage.

Diesel generators are common in off-grid power systems. Typical diesel generators consist of a diesel prime mover coupled to the shaft of a synchronous generator. Describe the role of an AVR in a diesel generator system, its components and how it may be modelled in a dynamic simulation.

A train runs between San Diego, and Kansas City, which is 4 km apart and maintains voltages of 450 volts and 400 volts respectively. The resistance of go and return is 0.05 ohm per km. The train draws a constant current of 500 A while in motion. What are the currents supplied by the two stations if the train is at the distance of minimum potential?

Design a clocked synchronous state machine with two inputs, A and B, and a single output Z that is 1 if
(1) A had the “different” value at each of the two previous clock ticks, or
(2) B has been 1 since the last time that the first condition was true.
Otherwise, the output should be 0.
Design a State assignment using decomposed process. Use D flip-flops , Design next-state logic using minimal 2-level NAND-NAND. When designing Next-state logic, don't consider multiple-output minimization.

?(?) = (? + 5)/[s(s+2)(s^2+6s+10)]

1. Sketch the root locus by hand. You may verify your sketch using MATLAB but you must show sufficient intermediate work for sketching.

2. Use MATLAB to identify the proportional controller value (to the tenth decimal point) that would cause your system to be unstable. Be sure to show evidence of this value. Plot your system response due to a step input for this controller.
