NEET Physics QUESTION #1046
Question 1
The output Y of the given logic circuit (NAND-NAND implementation) is similar to output of a ________ gate.
  • OR
  • NOR
  • AND✔️
  • NAND
Correct Answer Explanation
The circuit shows: A and B fed into a NAND gate, A also fed separately, and outputs combined into another NAND. Using Boolean algebra: NAND of two NANDs of (A,B) and (A,A) simplifies to AND. The output \(Y = \overline{\bar{A}+\overline{AB}} = A\cdot B\) (AND gate).
