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

  • AAll flip-flops are clocked by the common clock
  • BOnly the first flip-flop receives a clock
  • CEach stage is triggered only by the previous stage output
  • DNo flip-flops are used
Report an error
Correct Answer: A. All flip-flops are clocked by the common clock
Explanation: In a synchronous counter, all flip-flops receive the clock together and combinational logic determines which stages toggle. This avoids cumulative ripple clocking between stages.
Reference: Standard digital electronics: synchronous counters
