2.4. Compute and plot y[n] = x[n] * h[n], where x[n] h[n] = = 1, 0, 1, 0, 3≤ n ≤8 otherwise 4≤ n ≤ 15 otherwise 2.6. Compute and plot the convolution y[n] x[n] == (金) -n = x[n] h[n], where u[n 1] and h[n] = u[n-1]. 2.1. Let x[n] = d[n] + 28[n − 1] – 8[n - 3] and h[n] Compute and plot each of the following convolutions: (a) y₁[n] x[n] * h[n] (c) y3[n] = x[n] * h[n + 2] == = 28[n 1] + 28[n-1]. (b) y2[n] = x[n + 2] * h[n]
