FIGURE 15-2 Ап input signal sine wave of 0.5 volt peak and the unit pulse
train.
Figuгe 15-3 shows that the input sine wave that has а peak amplitude of 0.5 volt
when multiplied Ьу the unit-pulse-tгain signal гesults in а pulse tгain that has а
sampled sinusoidall outline ог envelope also with а O.5-volt peak amplitude.
