Question

Multichannel Analog Multiplexed System utilises time __________

(a) using a transformer

(b) using a capacitor

(c) using a flip-flop

(d) using a mux

I have been asked this question during an internship interview.

This interesting question is from Multiple Channel Data Acquisition System topic in section Data Acquisition System of Electrical Measurements

Answer 1

The correct choice is (d) using a mux

The explanation is: Multichannel Analog Multiplexed System is one type of multiplexed system. It makes use of a multiplexer (mux) to utilise the time. The previous data stored in the sample and hold circuit gets converted into digital form.
