2.1. Let

x[n] = 8[n] + 28[n 1]-8[n-3] and h[n] = 28[n+ 1] + 28[n − 1].

Compute and plot each of the following convolutions:

(a) yi[n] = x[n] *h[n]

(c) y3[n] = x[n] *h[n + 2]

(b) y2[n] = x[n+ 2] *h[n]/nQ.1 Textbook P.2.1 (a) & (b) modified. Compute each

of the following convolutions below (modified from

the textbook). Provide your answer in a

mathematical description and no need to plot it.

(a) y[n] = x[n]*h[n]

(b) y[n] = x[n+2]*h[n-1]
