Need this in MATLAB! Thank you.

1) Consider an LTID system with frequency response HIr] as depicted in Figure 3. For No 32 and ,-2n/No , plot H [r] with respect to 0. 0 -16 -12 -404 12 16 Figure 3 2) Find and plot the output yi[n] if the input xi[n] is applied to the system. For this purpose, find the DTFS of signal x[n] and then compute i[r]-Xi[r]H[] 1[n]-4cos(n/8) 3) Repeat part 2 for the signal x2In] defined below, x2[n]- 4 cos(n/2) 4) Compare the results in part 1 and 2 and discuss why they are different
