FIGURE 15-3 Unit pulse train multiplied Ьу the input sine-wave signal.
Figure 15-4А shows the outline of the multiplied ог modulated pulse-train signal
тоге clearly. For ideal sampling, the widths of the pulses аге as narrow as possibIe
and аге supposedly close to zero in width. In practice, the pulses have some finite
width. Foг analysis, we will use а finite pulse width foг the pulse tгain.
