1. Create a 4-bit Register
2. 1. This is very similar to your flip-flop design from lab task 1. Ensure that your 4-bit register has inputs “D” (dat, “CLK” (the clock), and “RST” (an asynchronous reset), and an output “Q”.
3. 2. [3 pts] Create a test bench and ensure that your 4-bit register operates correctly (test your reset signal and ensure that you can store a couple different values in the register). If your output behavior is correct, then copy your VHDL design code and simulation screenshot below:
4. 1. Place your 4-bit register’s VHDL design module code here (copy-paste as text, not an image):
5. 2. Place a screenshot of your simulation here (enlarge your waveform and do not crop the image (it should show the whole screen) or you will lose points):
6. 3. Explain why your circuit is (or is not) working correctly:

(a)Discuss the classification of logic families and their characteristic parameters.
(b) Design q mod -6 unit distance code counter using D flip flop.

True or False

The practice of engineering is regulated by the federal government  

Some forms of hearsay evidence are admissible.

A voidable contract is not a contract.

If there is unjust enrichment involved in a contract with a corporation the courts may establish a quasi-contract to effect a remedy.

The corporate veil affords complete protection for stockholders.

The offeror has the right to revoke the offer at any time

A false representation of a material fact is all that is needed to prove fraud

In general any preexisting duty is also sufficient consideration to support a contract.

3. Draw and explain the working principle of successive approximatin DVM digital voltmeter approach if used to measure dc voltage of 11.5 volts! Make a time diagram

Write an assembly language program for 8085 microprocessor to read consecutive memory locations from 2000 to 2FFF & transfer to 4000 to 4FFF

1. Define “Noise Factor”.

2. In an RF receiver system with cascaded amplifiers, where should most of the RF amplification take place, near the antenna or near the output? Why?

How to construct an impedance matrix and how to use its elements

I am working on a project where I need to close the solenoid valve (24DCV) at a different rate of time (variable closer time). It needs close very fast (at least within 50ms). I am using NI DAQ: USB-6211. Which relay should I use? Will digital relay timer work? Looking forward to your suggestions.

Matlab code would be greatly appreciated

Electromagnetic Waves:
Design single stub matching network for the transmission line of Zo = 50 ohms terminated with Z1 = 100+ j100 ohms. Find SWR and Reflection Coefficient .

A 650-nm continuous-wave laser beam strikes a photodetector. The photon arrival rate is 4x10^16 photons per second, resulting in 6x10^16 electrons per second being collected at the photodetector's positive contact (i.e.,anode).

1. What is the average received optical power in mW?

2. What is the average photocurrent in the external circuit?

3. What is the quantum efficiency of the photodetector?

4. What is the responsivity?

5. Does this photodetector exhibit photocurrent gain?
