Which statement correctly describes an asynchronous or ripple counter?

  1. All flip-flops receive the same clock signal directly
     
  2. The output of one flip-flop is used as the clock input for the next flip-flop
     
  3. It does not use flip-flops
     
  4. It always counts only one state

In an asynchronous counter, all flip-flops do not receive the same clock directly.

The first flip-flop receives the external clock.

Then the output of one flip-flop triggers the next flip-flop.

Because the change ripples from one flip-flop to another, it is called a ripple counter.
