Logic Gates

The output Y for the inputs A and B of the given logic circuit is:

Figure

Show answer and solution

Answer: (c)

  1. A NAND gate with joined inputs is a NOT gate: outputs Aˉ\bar{A} and Bˉ\bar{B}.
  2. Final NAND: Y=Aˉ⋅Bˉ‾=A+BY = \overline{\bar{A} \cdot \bar{B}} = A + B (De Morgan).
  3. So the answer is (c) A+BA + B.
