Question

In a ripple counter using edge-triggered $JK$ flip-flops, the pulse input is applied to

• A. Clock input of all flip-flops
• B. $J$ and $K$ input of one flip-flop
• C. $J$ and $K$ input of all flip flops
• D. Clock input of one flip-flop

Answer 1

In ripple counter using J-K flipflop with positive edge triggered, the output of one FF is fed as clock input the next FF. All FF are fed with inputs.

Hence the option C is correct.

Answer 2

option (c) is correct
