Question

In A/D converter, what is the time relation between sampling period T and the duration of the sample mode and the hold mode?

(a) Should be larger than the duration of sample mode and hold mode

(b) Should be smaller than the duration of sample mode and hold mode

(c) Should be equal to the duration of sample mode and hold mode

(d) Should be larger than or equals to the duration of sample mode and hold mode

This question was posed to me in an interview for internship.

The above asked question is from Sample and Hold in chapter Sampling and Reconstruction of Signals of Digital Signal Processing

Answer 1

Right option is (a) Should be larger than the duration of sample mode and hold mode

To explain: The A/D converter begins the conversion after it receives a convert command. The sampling period T should be larger than the duration of the sample mode and the hold mode.
