Question

In the absence of an S/H, the input signal must change by more than one-half of the quantization step during the conversion, which may be an impractical constraint.

(a) True

(b) False

The question was posed to me in an interview.

My doubt stems from Sample and Hold in portion Sampling and Reconstruction of Signals of Digital Signal Processing

Answer 1

Correct answer is (b) False

To elaborate: The use of an S/H allows the A /D converter to operate more slowly compared to the time actually used to acquire the sample. In the absence of an S/H, the input signal must not change by more than one-half of the quantization step during the conversion, which may be an impractical constraint.
