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.
