l. The 2 functions e(I)-cos(4π), e2 (t)-cos(16m) are sampled every T seconds. (4+5+6-15 pts) (i) In order that that they both be reconstructible from their samples, how large can Tbe? (ii) If T= 0.1, explain why the 2 transforms E(c) and E2(z) are equal, without actually computing the transforms. Note that cos(2/V-θ)-cos(θ). (iii) If T-0.1, mention how you will design a filter to include as part of the sampler in order to ensure that aliasing...

So this is the question I asked and this is the answer I got. I
still have a few doubts over the questions and would like
clarification.
Three things I want clarification on:
1) What are the assumptions made in part a and part b
2) A step by step clarification of the solving process of the
answer above
3) A solution to part B and an explanation on what is the
damping coefficient and what the comparison of the...
