Question

What does the triangle on the clock input of a j-k flip-flop mean?

Answer 1

Answer:

The triangle on the clock input of a J-K flip-flop mean edge triggered.

Explanation:

The triangle on the clock input of a J-K flip-flop mean edge triggered.

   The edge-triggered J-K will only accept the J and K inputs during the active edge of the clock.

   The small triangle on the clock input indicates that the device is edge-triggered.

   A bubble on the clock input indicates that the device responds to the negative edge. No bubble would indicate a positive edge-triggered device.

The JK Flip Flop -

The JK Flip-flop is similar to the SR Flip-flop but there is no change in state when the J and K inputs are both LOW
