Difference between RS flipflop and JK flipflop based on it basic operation.Explain

RS Flip-flop:

The circuit diagram and truth table of RS flip-flop are given below:

The truth table for SR flip-flops is:

 S R Q(t) Q(t + 1) 0 0 0 0 No changes 0 0 1 1 0 1 0 0 reset to 0 0 1 1 0 1 0 0 1 set to 1 1 0 1 1 1 1 0 Invalid Don’t care 1 1 1 Invalid

S = R = 0 is the normal resting condition of the SR flip-flop.

It has no effect on the output state of the flip-flop. Both Q(t) and Q(t+1) outputs remain in the logic state they were in prior to this input condition.

JK Flip Flop:

The circuit diagram and truth table of JK flip-flop are given below:

Truth Table for J-K flip flop is as follows:

 J K Q Q̅ Description 0 0 0 0 No Change 0 0 0 1 No Change 0 1 1 0 Reset to 0 0 1 0 1 Reset to 0 1 0 0 1 Set to 1 1 0 1 0 Set to 1 1 1 0 1 Toggle 1 1 1 0 Toggle

Observation:

From the above truth table, if the two inputs are high, then the output of SR flip flop is Don’t care but JK flip flop provides Toggled output.
