FIGURE 15-7 Sampling at the zero crossing of ап input signal.
For ап ideal sampling pulse-train signal, where the pulse duration is narrowed
toward О lJS, these glitches will trend toward zero.
Now let's take а look at sаmрliпg at а diffегепt portion of the input sigпаl, that iS,
viеwi'пgthе sampling at anotheг phase of the iпрut signal (Figuгe 15-8). In the
figure, since the peak amplitude of the phase-shifted siпе wave is about one-half
the amplitude of the "unit" sampling pulses, the output should show а tгаiп of
pulses of about one-half height (Figuгe 15-9).
