Explain the advantages and disadvantages for each method of speed control: Variable stator voltage control, Rotor resistance control, Frequency control.

Excuse me teacher, could you help me to answer these questions by typing but not writing?
Thanks teacher.

Write a summary on phase-shifters in GHz range.

pls, I need Matlab code for, OFDM modulation (Matlab demo by at least 4 carriers)

What is ram (in computer desktop)? why do we need ram?

so, If I have to analysis Ram 36 GB (8GB x4) DDR4/ 3000 MHZ.

what is 36 GB of ram? what is DDR4? and what is 3000 MHZ?

What are the differences between the programming languages of VHDL and Verilog? Why use one over the other?

Describe a graph abstraction (e.g., the world-wide-web can be modeled as a graph where vertices are web pages and edges are hot-links). Describe one not discussed in the course material. For this graph, describe the meaning of a shortest hop path, diameter, and degree.

Let A be a three-bit unsigned number. Use a seven-bit adder (and NOT gates, as necessary) to design a circuit that calculates the following operations. Note that the output may be assumed as unsigned, unless it is possible for the operation to produce a negative answer, in which case, the output must be correct in 2’s complement:

W = 3A + 1

X = 2A – 17

Y = 40A + 6

Z = 32 – 4A

Calculate the energy per bit per noise power density where the signal power is 10 Watts and the bit is 10 Mbps in an environment of 27 degree celcius?

Q1: How to draw phasor diagrams for a transformer to find an unknown value?

Q2: What are the circuit parameters for an open circuit test and short-circuit test given the current, voltage, and power for these test?

Q3:How can we relate the ratios(the winding, current, and voltage relationship) with the circuit parameters discussed above?

Q4: Explain what it means to find high side and low side in a practical transformer.

With appropriate waveforms and a few sentences describe how a grid connected 4 quadrant VSCC inverter can supply active power, capacitive reactive power and inductive reactive power and where this may be useful in grid power quality control.

what is 5s + 1s and how can apply in process

An FIR system produced an output y[n] as given below for an input x[n] = {1,1,1,1}, y[n] = {6,11,15,18,14,10,6,3,1}. Find the FIR system.

Use bk, d(n-k) equation if applicable. Thanks!

Design an up/down counter with four states (0, 1, 2, 3) using clocked JK flip flops. A control signal x is used as follows: When x = 0 the machine counts forward (up), when x = 1, backward (down). Simulate using MultiSim and attach a simulation printout.

Please address the following:

1. State Table
2. State Diagram
3. Flip Flop Excitation Tables
4. K-Map Simplification and Resulting Diagram
5. MultiSim Simulation

1. Two electric charges, the first value + 3Q and the second value + 2Q are separated by a known distance d. What load and at what distance from the first load should a third collinear load be placed with the other two, so that the three-load system is in equilibrium?

2. What is the force exerted on the load Q of the corner of a cube of side a, if in each corner of the cube there are loads of value Q (In total there are 8 loads in the cube)?

3. At point (0, a) there is a load + 2Q and at point (b, 0) a load of value -3Q. What is the value of the electric field (as a vector) at the following points: (a, a), (b, b), (0,0)?
