Question

What is the purpose of one shot multivibrator?

(a) Trigger all AND gates at clock frequency

(b) Trigger all OR gates at clock frequency

(c) Trigger all AND gates at signal frequency

(d) Trigger all OR gates at signal frequency

I had been asked this question during an internship interview.

Enquiry is from Time Division Multiplexing topic in portion Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics

Answer 1

The correct choice is (a) Trigger all AND gates at clock frequency

To elaborate: The one-shot multivibrator is used to trigger all the decoder AND gates at the clock frequency. It produces an output pulse whose duration has been set to the desired sampling interval.
