Question

In a J-K flip-flop we have J = $\overline{Q}$ and K = 1 (see figure). Assuming the flip-flop was initially cleared and then clocked for 6 pulses, the sequence at the Q output will be

Answer 1

When, Q = 0 $\to$ $\overline{Q}$ = 1
So, J = K = 1
$Q_{n+1}$ = ${\overline{Q}}_n$ = 1
When
Q =1 $\to$ $\overline{Q}$ = 0
J = 0, K = 1
$Q_{n+1}$ = 0
So, the sequence at the Q output will be 0 1 0 1 0 1.
