For each of the positive edge-triggered JK flip-flop used in the following figure, the propagation delay is ∆T.
Which of the following waveforms correctly represents the output at Q1?
-
- 1
- 2
- 3
- 4
- 1
Correct Option: B
The output of flip-flop is one fourth of the CLK frequency and 2∆T is the propagation delay of 2 flip-flops.
