For one of the following conditions, clocked J-K flip-flop

For one of the following conditions, clocked J-K flip-flop can be used as a divide-by-2 circuit when the input signal is applied at clock-input—

1. J = K = 1 and flip-flop has active-HIGH inputs
2. J = K = 0 and flip-flop has active-HIGH inputs
3. J = K = 1 and flip-flop active-Low inputs
4. J = K = 1 and flip-flop should be a negative edge triggered.

The clocked J-K flip-flop can be used as a divide-by- 2 circuit when input J = K = 1 is applied at clock input and flip-flop has active HIGH inputs.
