Q. Sample – and – hold circuits in analog to digital converters (ADCs) are designed to :
Solution:
In electronics, a sample and hold (S/H, also “follow-and-hold”) circuit is an analog device that samples (captures, takes) the voltage of a continuously varying analog signal and holds (locks, freezes) its value at a constant level for a specified minimum period of time. Sample and hold circuits are typically used in analog-to-digital converters to eliminate variations in input signal that can corrupt the conversion process.
