Logic Gates question from JEE Main 2023 (13 Apr, Shift 1)

Q95JEE Main 2023 · 13 APR · SHIFT 1Medium

Logic Gates

For the following circuit and given inputs A and B, choose the correct option for output ' $Y$ '

Show answer and solution

Answer: (d)

NOR with joined inputs gives $\bar{A}$ ; OR with joined inputs gives $B$ .
$Y = \overline{\bar{A}B} = A + \bar{B}$ , so $Y = 0$ only when $A = 0, B = 1$ .
From the waveforms, $A = 0, B = 1$ only between $t_1$ and $t_2$ .
So $Y = 1$ everywhere except $0$ from $t_1$ to $t_2$ . So the answer is (d).
