In a preset table counter using J-K flip flop, what signal is applied to the J and K inputs? Correct Answer Logic 1

A preset table counter is a type of counter circuit where any randomly desired state can be set as the starting state by the user. Assigning logic 1 to both the inputs of a J-K flip flop takes it to toggle state. This toggle states of the used flip-flops are necessary for the counter operation.
