## How to design a JK Flip-Flop (electronic circuit)?

You can easily design the JK Flip-Flop circuit by practicing the exercises given below. Here you can design and simulate your own electronic circuits with this Online Circuit Designer and Simulator.

### Circuit Description:

This circuit is a JK flip-flop. It only changes when the clock transitions from high to low. The inputs (labelled J and K) are shown on the left. When J = K = 0, it holds its present state. When J = 1, K = 0, the output is set to high. When J = 0, K = 1, the output is set to low. When J = K = 1, the output is toggled from high to low (or low to high). -- Credits: Mr. Paul Falstad.
