For the logic circuit shown, the truth table is:

Options

  1. AA B Y 0 0 0 0 1 1 1 0 1 1 1 1
  2. BA B Y 0 0 1 0 1 1 1 0 1 1 1 0
  3. CA B Y 0 0 1 0 1 0 1 0 0 1 1 0
  4. DA B Y 0 0 0 0 1 0 1 0 0 1 1 1

Correct answer

D. A B Y 0 0 0 0 1 0 1 0 0 1 1 1

Step-by-step solution

Y = A ¯ + B ¯ ¯ = A ¯ ¯ . B ¯ ¯ = A . B = AND A B Y 0 0 0 0 1 0 1 0 0 1 1 1
