A flat-top sampler can be represented as the block diagram of Figure 2.40.
(a) Assuming Ï„ << T_s, sketch the output for a typical x(t).

(b) Find the spectrum of the output, Y(f), in terms of the spectrum of the input, X(f). Determine the relationship between Ï„ and T_s required to minimize distortion in the recovered waveform?. x(t) X5 (t) h(t) = Y(1) = x,(1) * II(4 - 7)/ 7] Пс-3»я E 8 (t – nT,) 00 n=-00 Figure 2.40

x(t) X5 (t) h(t) = Y(1) = x,(1) * II(4 - 7)/ 7] -3 E 8 (t nT,) 00 n=-00 Figure 2.40
