Q78 / 90 · JEE Main 2022 (25 Jun Shift 2) · Physics

Identify the logic operation performed by the given circuit

Correct answer
A
AND gate
B
OR gate
C
NOR gate
D
NAND gate

Solution

According to the circuit,

Output $= \bar{\bar{A} + \bar{B}}$

$\begin{aligned} = \bar{A} \cdot \bar{B} \\ = A \cdot B \end{aligned}$

Thus, the given circuit is a AND gate.

Hence, the correct answer is option: 'A'.
