A 4-bit ripple counter consists of flip-flops, which each have a propagation delay from clock to Q output of 15 ns. For the counter to recycle from 1111 to 0000, it takes a total of ________.-A-15 nsB-30 nsC-45 nsD-60 ns-D-60 ns

Question

APTITUDE CRACK · Accepted Answer

D 60 ns Kindly note that, the given counter is ripple(asynchronous), So only it would take 4*15 = 60ns. If it is synchronous counter, it would take 15ns, to come out the results.
