Can someone help me with the matlab code of this question.

= { Frequency-domain sampling. Consider the following discrete-time signal Jah, In L x(n) = 0. Inl > L where a = 0.95 and L = 10. (a) Compute and plot the signal x(n). (b) Show that L **(x). X(@) = x(n)e-jon = x (0) + x(n) cos en 11-1 Plot X(w) by computing it at w = nk/100, k = 0, 1, ..., 100. (c) Compute -X k = 0,1,..., N-1 for N = 30. (d) Determine and plot the signal N-1 (n) = {ckej (27/N)kn k=0 What is the relation between the signals x(n) and i(n)? Explain. (e) Compute and plot the signal xi (n) = -x *(n-IN), -L
