Flip-Flops

Q1:

With four J-K flip-flops wired as an asynchronous counter, the first output change of divider #4 indicates a count of how many input clock pulses?

A 16

B 8

C 4

D 2

ANS:B - 8

With four J-K flip-flops wired as an asynchronous counter, the first output change of divider #4 (i.e 4th f/f) indicates a count of how many input clock pulses?

So when 4th f/f has o/p 1 then count is 1000 and it counted 8 clock pulses.
