Question

(a) First create an estimate of the powerspectral density of x[k] by using the periodogramestimate.

(b) When doing part (b), useParseval’s theorem to calculate the total average power ofx[k] in 2 different ways. Show that they areequivalent.

(c) Now, create a modified averageperiodogram estimate. Try using a Hamming window with length 128,with 50% overlap. Create a plot, comparing this modified averageperiodogram with the periodogram estimate ofpart(a).

(d) See what happens when you modify some ofthese parameters (window

type, window size, overlap) – You donot have to turn in results for this part (part(d)).

Explanation / Answer

hello you have a prettu hard problem on your hand . see I can help but sometimes I git in trouble for helping on cramster.com anyways . for part a ) make sure you add the noise into the signal : meaning just plotting y(x) doesn't add noise to you signal . used rnadn in matlad to add noise when is your home work due?
