JEE Mains · Physics · STD 12 - 14. Semicondutor electronics
If \(X\) and \(Y\) are the inputs, the given circuit works as _______.

- A OR gate
- B AND gate
- C NAND gate
- D NOR gate
Answer & Solution
Correct Answer
(D) NOR gate
Step-by-step Solution
Detailed explanation
The circuit consists of four NAND gates. The first two NAND gates have their inputs tied together, acting as NOT gates. Their outputs are \(\overline{X}\) and \(\overline{Y}\). These outputs are fed into the third NAND gate. The output of this gate is:…
