A synchronous counter differs from a ripple counter because in a synchronous counter?

  • AOnly the first flip-flop receives the clock
  • BAll flip-flops are clocked simultaneously
  • CNo flip-flop requires a clock
  • DThe output is always asynchronous
Report an error
Correct Answer: B. All flip-flops are clocked simultaneously
Explanation: In a synchronous counter, the same clock is applied to all flip-flops, so state changes occur together rather than rippling stage by stage.
Reference: Standard digital electronics: synchronous counters
