<p>The highest frequency of signals that can be sampled by a former-stage sampling hold part is higher than the highest frequency of signals that can be sampled by a latter-stage sampling hold part. The former-stage sampling hold part, therefore, can respond to an input signal at a higher rate. That is, even when the input signal has a high frequency, the former-stage sampling hold part can sample the signal level of the input signal in a precise manner. The latter-stage sampling hold part exhibits a smaller rate of change relative to the time of the sampled signal level than the former-stage sampling hold part, and hence can hold the sampled signal for a longer time than the former-stage sampling hold part.</p> |
