If the above function is implemented using D flip-flop, then

  1. $ D_A = \bar AB + \bar BC + AC$
  2. $ D_A = A \bar B \bar C + BC$
  3. $ D_A = ABC + AB$
  4. $ D_A = A \bar B + C \bar A$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

$J_A = \bar ABC + AB\bar C = B (\bar C + A\bar C) $ $K_A = A + \bar A\bar C$
$D = A\bar B\bar C + BC $
