For realisation of SR flip-flop from JK flip-flop, if S=1, R=0 & present state is 0 then the excitation input will be ___________(a) J=1, K=1(b) J=X, K=1(c) J=1, K=X(d) J=0, K=0The question was asked in an interview for job.This intriguing question originated from Realisation of one Flip-flop using other Flip-flops topic in section Flip-Flops of Digital Circuits

Answer» RIGHT CHOICE is (c) J=1, K=X

To elaborate: For realisation of SR flip-flop from JK flip-flop, if S=1, R=0 & PRESENT state is 0 then the excitation input will be J=1, K=X.
