In an FIR digital filter, each sample in the output signal is found by multiplying M samples from the input signal by M predetermined coefficients, and adding the products. The characteristics of these filters (high-pass, low-pass, etc.) are determined by the coefficients used. For this problem, assume M = 5000, and that single precision floating point math is used. a. How many math operations (the number of multiplications plus the number of additions) need to be conducted to calculate each point in the output signal? b. If the output signal has an average amplitude of about one-hundred, what is the expected error on an individual output sample? Assume that the round-off errors combine by addition. Give your answer both as an absolute number, and as a fraction of the number being represented. c. Repeat (b) for the case that the round-off errors combine randomly. Explain in detail?

A) List the advantages and disadvantages of synchronising an AC generator to the utility
grid.
B) Describe the importance of frequency control for synchronous generators.
C) List the important applications of synchronising AC generator to the utility grid

Use JK-Flip-Flop to design a sequential circuit as an input for the previous designed decoder to write UAE. In this design, the sequential circuit will be used instead of the two bits switches and the output will be shown in three 7-segment displays one for each letter. Letters must glow one by one in a correct sequence where the speed depends on the clock frequency.

Use only one circuit as an input for the three 7-segment displays where one of them is ON while the others are OFF at each state depends on the letter itself.

Construct the truth table for this problem, derive the J and K expressions for all FFs, and implement your design using basic logic gates and three CK seven segment displays. Check your design by simulation (Multisim) and be ready to implement it practically in the lab.

Hint: In this design you need only two JK-FFs, one 2-inputs OR, and one 2-inputs XOR

The nature of lake is that there is a giant explosion of what are called “midges” in the mid to late summer. If you haven’t been around and seen these bugs:

Your car gets covered so bad that you can’t see out the windsheild after driving 10 miles! They get everywhere; don’t open your door at night as they flood in! Now althought this is seen as a menace from bug hell, there are some not so obvious advantages which come from this menace. Who see the bugs, catch them and feed them to their young. And Who “see” bugs through sonar,their voices are their “eyes and ears”.

Professor from the Environmental program is trying to get an estimate of the population of bats that are around the lake to quantify the relationship and population dynamics of bats to the severity of the menace. Now bats are night creatures you see, well he can’t see so well as it is night! He is at a conundrum for how to measure the number of bats in a given area. Very difficult to do as you can’t visually (unless you have a light, yet this will probably throw off the count of bats as the bugs are attracted to the light, hence bats also, yet this would lead to an unnatural or not normal distribution of bats!) so he must be away from the street lights further down the road and the lights from cars with that blasting stereo to drowned out the new street performance muffler shouldn’t affect the natural distribution of bats. The second issue is that bats don’t fly in formation, they come from all directions almost randomly. Prof. has come to you for a solution to his bat count problem. Using the knowledge you have gained, come up with a simple design to help Prof. count his bats. Describe your solution and reasons why you chose this solution. Include any calculations and a concluding paragraph of what you have learned in this problem.

Use and provide Matlab for the following: Generate the discrete-time signal x[n] = 4 cos (2pi. 10. nT5) + 2cos(2pi. 100. nT5) + 3cos(2pi 200. nT's), with Ts0.001 sec. Display the signal in both time and frequency-domain. Assume that the 100 Hz component of x [n] is your desired signal while the other two components are noise. Design a suitable filter to extract the desired (i.e. 100 Hz) signal. Display the filter's response. Display the output signal in the frequency-domain. Display the time-domain input and output signals in the same plot.
