technology?

code an 8 bit LFSR random number generator in system verilog. Write a test bench, load the seed 11111111, and generate the first 10 random numbers.

You are tasked with designing an ICS/SCADA system. You must choose a type of ICS/SCADA system from the options listed below:

Correctional facility

Paint processing plant

Water distribution facility

Considering the type of system you chose from the list above, discuss the model you would use (time or event-based or a combination) and for what purposes. What considerations do you need to take into account in your design? How does the PLC fit into this system?

how do you know your product is a good one and how do you sell the idea to an investor?

V. How does ARM processor differentiate between a timer interrupt and an A/D interrupt?

VI. What does privileged mode mean and what is the major difference between this mode and non-privileged mode?

VII. There are two interrupt pins on ARM microprocessor: IRQ and FIQ. Which one can interrupt the other one and why?

DO IT To receive credit for this assignment, each problem must be computed using a MATLAB script. Do not hard-code computations. Define variables for the parameters given in the problem, and use MATLAB to calculate necessary intermediate and final output variables. Inlcude the MATLAB Code. A 200-mi. transmission line has the following parameters at 60 Hz: Resistance, r = 0.24 Ω/mi. per phase Series Reactance, x = 0.71 Ω/mi. per phase Shunt Susceptance, b = 5.42 × 10−6 S/mi. per phase Determine the signal wavelength λ and the propagation constant γ, attenuation constant α, phase constant β, and characteristic impedance Zc of the transmission line at 60 Hz using the general expressions in terms of Z and Y parameters valid for conductance G = 0 S/mi. Next, calculate the “convenient” artificial value for conductance G = RC/L and α, β, and Zc using this approximation. Finally, determine the sending-end voltage and current if the line is open-circuited and the receiving-end voltage is 100 kV line-to-line.

VHDL Code: Design a 16-bit 4-to-1 multiplexer using data-flow implementation style. Data inputs and output should be 16-bit vectors. In your test bench, you should include enough number of test cases to show the correctness of your design.

Renewable Energy Engineering Question:

Q) If the sun goes down, what other forms of renewable energy can be used to help provide a continuous flow of power to the grid?

Task 2 (P1.2)

For this task you are required to summarize the use of microcontrollers in each of the following applications. Indicate the general purpose and the main advantage of using a microcontroller.

Arcade games

Mechanical dolls (for example, Tickle Me Elmo)

Toy drones

Each of these must be at least one written paragraph. You are required to cite your sources.

1.Will an oscilloscope interfere with a circuit under test? Justify your answer.

2.For a dual power supply, show the necessary connection to obtain -5V and -8V with respect to a common (chassis) ground. Repeat for -5V and +8V.

3.Explain the use of the current limiting feature for the dual-voltage power supply.

4.What happens to the output current and voltage when the power supply is shorted?

5.Explain the function of the AC/DC selector on the DMM.

If you were to design a communication system for voice frequencies, explain which modulation technique you would use for the following cases: Very high Immunity to noise and interference is important Narrow signal bandwidth is important, Simple and a cheap electrical receiver is importance. In your opinion, which technique is the most expensive and why?

Using the indicated parameters for each system element (P in, G1, L & G2) and with impedances matched for each junction (node, Ni ) of this end-to-end system, compute a) the net linear system gain, b) the net system gain in dB, and c )the power levels (in dB) at each stage of this cascaded system (i.e. Pin, N1, N2, and P out). Pin=0.1 W, G1=400, L=2,000, G2=500

VLSI circuit design

integrated ciruit : fabrication and manufacturing in industry

imulate/ code in verilog:

Develop an electronic key system using the FSM (moore) methology. Use from student ID and use the last 4 digits:(0864)

if the number is <5 then = 1

if the number is >=5 then = 0

example: 8012345. Take last 4 digits (2345) which makes it 0001.

In my case, the last 4 digits are 0864, which makes it 0110

features of FSM (moore FSM):

input 4 bits serially,

if the sequence is correct, then you proceed to next state. Otherwise, go to error state, then go to rest state
