The Scientific Working Group on Digital Evidence develops best practice and standard documents for digital forensics. What are three important digital forensic standard practices that an organization starting a digital forensic unit should implement? Why?

1) A 25 kVA transformer supplies a load of 12 kW at power factor of 0.6 lagging. How much kVA can be added before the transformer is at rated load

a)when the added load is at 1.0 pf?

b)when the added load is at 0.866 pf leading?

A 2000 v signle phase synchorunus generator isbeing used as a backup generator outside a diagnostic center in Islamabad . when the generator terminals are short circuited and a field exication current if 2.5 A is passed, the ammeter between the terminals read 100 A of full load current . if this terminals of the same generator are opened and the voltage across them is measured using a voltmeter , we get the value of 500V with the same exciatation cureent . the armature resistance is 0.8 ohms.

Determine the voltage regulation of this generator if it is delivering 100 A during normal operating with unity power factor , 100A with 0.8 leading PF and with 0.71 lagging PF

Plz explain. I will rate.

1. Explain the following terms with respect to TTL specifications:

1. Propagation Delay
2. Power Dissipation
3. Fan-in
4. Fan-out

list one question you have about the operation of an automotive voltage regulator. (from textbook "fundamentals of electrical engineering"  chapter 2.8)

Your question may range from how the VR is modeled to what the implications are for removing the VR in the system.

Then, Using online resources/other texts, briefly answer your question to the best of your ability.

what is a ZOH equivalent DC system?
list three types of quantization errors

write a programme named question5a.cpp that calculate and print pay slip

Produce a brief description to the sources of non linearity in control systems ((mentioning its effect on the system response))

Try designing a 4 bit Multiplexer using two 2-bit multiplexer design given below and verify the design by simulating it.

module Mux2x1(In0,In1,sel,out);
input In0,In1,sel;
output out;
assign out = (sel)?In1:In0;
endmodule

Pls include the verilog design module,testbench, waveform

21a. Draw the state graph and corresponding transition table for a 3-bit counter with no control inputs that counts in multiples of 3. That is, the count sequence is: 000-011-110-000-.... Use don't cares in the transition table as appropriate.

b. Draw the state graph and corresponding transition table for a 3-bit binary counter with no control inputs which counts down rather than up. Include a Z output which signifies when the "count value modulo 3 is equal to 0."

c. Draw the state graph for a 3-bit up/down counter which has the following inputs: CLR, INC, DEC. Make it so the inputs have priority in that order. Add a Z output which signifies whenever the current state of the counter is either '010' or '110'.

Design a circuit using Op amp that will combine four voltages according to the following ratio. You can only use invertor amplifier . All input voltages are positive and you cannot tamper with the sources V_o = 4V₁ - V₂ - 8V₃ - 2V₄

You have a camera that is sensitive in the visible light range. Your 3D printing
facility has informed you that all inks are out except the transparent type. Your group
mates try to paint or attach opaque black tape to the printed transparent ink, but only
small, tiny pieces manage to stick and you cannot cover the box with such pieces - it is
too much work. To make matters worse, your assignment to make a pinhole camera is
due tomorrow and you did not work on it, even though the instructor warned you
multiple times about this.
Suddenly you realize that you could create a "negative pinhole" or pinspeck camera, by
blocking the light that would have been collected by a pinhole camera.
a) How do you implement your pinhole camera?
b) Does it have any limitations?

On January 1, Frank bought a used car for $7200 and agreed to pay for it as follows: 1/4 down payment; the balance to be paid in 36 equal monthly payments; the first payment due February 1; an annual interest rate of 9%, compounded monthly. (a) What is the amount of Frank’s monthly payment? (b) During the summer, Frank made enough money to pay off the entire balance due on the car as of October.
