The output (YY) of the given logic gate circuit is similar to the output of a/an:

Question 33 as printed in the NEET 2024 booklet

  1. A.NOR gate
  2. B.OR gate
  3. C.AND gate✓
  4. D.NAND gate

Solution

The upper gate has both inputs tied to A, so it outputs Aˉ\bar A; the lower NOR with both inputs B outputs Bˉ\bar B. The final NOR gives Y=Aˉ+Bˉ‾=A⋅BY = \overline{\bar A + \bar B} = A \cdot B — an AND gate.
