Question

A down counter using n-flip-flops count ______________

(a) Downward from a maximum count

(b) Upward from a minimum count

(c) Downward from a minimum to maximum count

(d) Toggles between Up and Down count

I have been asked this question during a job interview.

My doubt stems from Asynchronous Down Counter topic in chapter Counters of Digital Circuits

Answer 1

Correct option is (a) Downward from a maximum count

To explain I would say: As the name suggests down counter means counting occurs from a higher value to lower value (i.e. (2^n – 1) to 0).
