Counters - Technical MCQs

Q1:

Synchronous counters eliminate the delay problems encountered with asynchronous counters because the:

A input clock pulses are applied only to the first and last stages

B input clock pulses are applied only to the last stage

C input clock pulses are not used to activate any of the counter stages

D input clock pulses are applied simultaneously to each stage

ANS:D - input clock pulses are applied simultaneously to each stage

In Synchronous counters, clock is applied simultaneously to all the stages therefore delay time is reduced.

In Asynchronous counter, clock is applied to only first stage & next stage depends on the response of the previous stage that causes delay.
