1. Problem 7.1.
2. Problem 7.4. Use MATLAB to plot the amplitude and phase spectrum.
3. Problem 7.5 (a) (f) (g) (h).
4. Problem 7.6 (a).
5. Problem 7.8. Note: Rx[n] = x[n]*x[-n].
6. Problem 7.9 (a) (c) (e) (g). (Do (g) for (a), (c), (e)). Note: You can use the MATLAB function fft rather than the dft m-file to find the DFT.
7. For the sequence x[n] of Problem 7.4 (b), use MATLAB to plot the 16-point DFT of the first 16 points of x[n], i.e,. x[n] for n = 0 through 15. Plot X(Omega) from 0 to 2 pi. Plot the 16-point DFT of x[n] on the same graph to compare the DFT of the truncated sequence to the DTFT.
