Which of the following enables us to eliminate the undefined state in an SR latch?Group of answer choicesNoneT flip - flopD LatchJK flip - Flop
Solution
The undefined state in an SR latch can be eliminated by using a JK flip-flop. The JK flip-flop is a refinement of the SR flip-flop where the indeterminate state of the SR type is defined in the JK type. The JK flip-flop augments the behavior of the SR flip-flop (J=Set, K=Reset) by interpreting the S = R = 1 condition as a "flip" or toggle command. Specifically, the combination J = 1, K = 1 is a command to toggle the state of the flip-flop.
