Sample and Hold circuit

The sampling circuit and the holding circuit generate electrical samples as input and then hold these samples for a specified period. The time at which the sample and circuit holder produces the input signal sample is called the sampling time. Correspondingly, the length of the circuit that holds the sampled value is called the holding time.
