Q1:

Using the same flip flops

A a synchronous flip flop can operate at higher frequency than ripple counter

B a ripple counter can operate at higher frequency than synchronous counter

C both ripple and synchronous counter can operate at the same frequency

D can not determine

ANS:A - a synchronous flip flop can operate at higher frequency than ripple counter

In a synchronous counter clock pulses are applied to all flip-flops simultaneously. Hence minimum time delay and high frequency.
