Logic Gates

The resultant gate and its Boolean expression in the given circuit is

Figure

Show answer and solution

Answer: (b)

  1. NOT gates give C=AˉC = \bar A, D=BˉD = \bar B.
  2. NOR: Y=Aˉ+Bˉ‾=A⋅BY = \overline{\bar A + \bar B} = A \cdot B (De Morgan).
  3. So the answer is (b) AND, A⋅BA \cdot B.
