JK flip flop

The JK flipflop builds on the SR flipflop by adding a toggle function when both inputs are 1. The S (set) and R (reset) inputs are now referred to as J (set) and K (reset) to indicate the different operation. In other words: J1, K0 sets the flipflop J0, K1 resets the flipflop J1, K1 toggles the flipflop The toggling function is useful for building counter circuits which we ll do in future videos.
