The characteristic equation of an SR flip-flop is given by
(A) Qn+1 = S + RQn
(B) Qn+1= RQ\’n + SQn
(C) Qn+1= S\’ + RQn
(D) Qn+1 = S + R\’Qn
Answer: (D)
Explanation: The characteristic table of an SR flip-flop is:
So, by simplifying using k-maps:
characteristic equation of an SR flip-flop = Qn+1 = S + R\’Qn
Option(D) is correct.
