A 4 bit ripple counter and 4 bit synchronous counter are made using flip-flops having a propagation delay of 10 nsec each. If the worst case delay in the ripple counter and the synchronous counter be R and S respectively, then:
Answer: C. R = 40 nsec, S = 10 nsec
- A.
R = 10 nsec, S = 30 nsec
- B.
R = 30 nsec, S = 10 nsec
- C.
R = 40 nsec, S = 10 nsec
- D.
R = 10 nsec, S = 40 nsec
