Figure 2.41 illustrates so-called zero-order-hold reconstruction.

(a) Sketch y(t) for a typical x(t). Under what conditions is y(t) a good approximation to x(t)?

(b) Find the spectrum of y(t) in terms of the spectrum of x(t). Discuss the approximation of y(t) to x(t) in terms of frequency-domain arguments.
