Question:

In the system shown in Figure,?

H_c(t) =?(t ? T/2).

(a) Suppose the input x[n] = sin(? n/2) and T = 10. Find y[n].

(b) Suppose you use the same x[n] as in part (a), but halve T to be 5. Find the resulting y[n].

(c) In general, how does the continuous-time LTI system h_c(t) limit the range of the sampling period T that can be used without changing y[n]?
