JK Flip Flop - Basic Online Digital Electronics Course It is a circuit that has two stable states and can store one bit of state information. The output changes state by signals applied to one or more control inputs. The basic JK Flip Flop has J,K inputs and a clock input and outputs Q and Q (the inverse of Q). Optionally it may also include the PR (Preset) and CLR (Clear) control inputs. The truth table and diagram Ripple Counter in Digital Logic - GeeksforGeeks A 3-bit Ripple counter using JK flip-flop – In the circuit shown in above figure, Q0(LSB) will toggle for every clock pulse because JK flip-flop works in toggle mode when both J and K are applied 1, 1 or high input.
