Logic Gates question from JEE Main 2024 (29 Jan, Shift 2)

Q74JEE Main 2024 · 29 JAN · SHIFT 2Medium

Logic Gates

The truth table for this given circuit is:

Show answer and solution

Answer: (b)

Upper AND gets $A$ and $B$ : $AB$ . Lower AND gets $\bar{A}$ and $B$ : $\bar{A}B$ .
$Y = AB + \bar{A}B = B(A + \bar{A}) = B$ .
Output column copies B: $0, 1, 0, 1$ for $00, 01, 10, 11$ .
So the answer is (b).
