The flip flop is a basic building block of sequential logic circuits. The obvious advantage of this clocked SR flip-flop is that the inputs R and S are considered only when the clock pulse is high. In many applications, it is desired to initially Set or Reset the flip flop. It has two inputs S and R and two outputs Q and. I can now understand flip flop……. Luis N. Like the in depth explanations.

Our Apps. No Change. Reset to 0. The JK flip flop work in the same way as the SR flip flop work. The only difference between JK flip flop and SR flip flop is that when both inputs of SR flip flop is set to 1, the circuit produces the invalid states as outputs, but in case of JK flip flop, there are no invalid states even if both 'J' and 'K' flip flops are set to 1. The invalid or illegal output condition occurs when both of the inputs are set to 1 and are prevented by the addition of a clock input circuit.
So, the JK flip-flop has four possible input combinations, i. It means the J and K input equates to S and R, respectively. The third input of each gate is connected to the outputs at Q and Q'. Since Q and Q' are always different, we can use them to control the input. When both inputs 'J' and 'K' are set to 1, the JK toggles the flip flop as per the given truth table. The JK flip flop work as a T-type toggle flip flop when both of its inputs are set to 1.
The JK flip flop is an improved clocked SR flip flop. But it still suffers from the "race" problem. This problem occurs when the state of the output Q is changed before the clock input's timing pulse has time to go "Off". We have to keep short timing plus period T for avoiding this period.
