A counter in which all the flip-flops receive the clock pulse at the same time is known as

  • A.ripple counter
  • B.synchronous counter
  • C.clocked counter
  • D.asynchronous counter

Answer: B

A synchronous counter has the same clock pulse applied to all its flip-flops at the same instant, so all the stages change state together and there is no cumulative propagation delay. In a ripple (asynchronous) counter each flip-flop is clocked by the output of the one before it, so the delays add up. 'Clocked counter' is not a standard type of counter. The answer is a synchronous counter.
