The figure shown a digital circuit constructed using negative edge triggered J-K flip flops. Assume a starting state of Q2Q1Q0 = 000. This state Q2Q1Q0 =000 will repeat after _______ number of cycles of the clock CLK
-
- 2
- 4
- 6
- 8
Correct Option: C
First flip flop acts as mod-2 counter Second 2 flip flops from mod (2n-1) Johnson counter = mod counter
∴ overall modulus = mod – 6 counter
