. (a) Draw the graph of f(t) starting from fo=0 when v; = 1, -1, −1, 1, ... (j = 1, 2, 3, 4, ...). If v has period 4, find f(12), f(13), f(100.1). (b) For the discrete sine f; = 0, 1, 1, 0, -1, -1, ... when j = 0, 1, 2, 3, 4, 5, ..., find the second differences a1=f2-2f1+fo, a2=f3-2f2+fi, and a3. Compare a; and fj. .
