(a) Do the following two circuits have essentially the same timing?
(b) Draw the timing for Q_aand Q_bgiven the timing diagram.

(c) If your answer to (a) is no, show what change(s) should be made in the second circuit so that the two circuits have essentially the same timing (do not change the flip-flop).
