Question 5
An 8–point signal π₯[π] is shown in Figure 2.
i. Using MATLAB compute DFT of π¦[π] = π₯[π + 1] i.e., π[π].
ii. Plot DFT magnitude and phase as functions of k.
iii. Compute and plot the IDFT of π[π].
Question 6
Record the audio for first three letters of your name. e.g., M A H for MAHMOOD
i. Save this audio file on MATLAB in vector x and plot vector x using plot(t, x). where t is time.
ii. Perform DFT on vector x, using fft command in MATLAB and plot the amplitude spectrum.
ii. Perform DFT on vector x, using fft command in MATLAB and plot the amplitude spectrum.
