Hi, I am trying to understand and analyze JK flip flop's (using RS flop flop i.e. using NOR gates). I have written out the characteristic table and when I give Q = 1, J=1 and K = 0 I am trying to analyze the Q' (Q complement) by giving the intial state to 0. I find that Q settles to 1 (i.e. Q(t+1)) but Q' oscillates between 0 and 1. How is this fixed? Is the Q' needed in JK flip flops? Also why do textbooks don't talk about Q' in JK or D or T but only Q and Q(t+1) ? Thanks.
