Logic Gates

Identify the correct output signal Y in the given combination of gates (as shown) for the given inputs A and B.

Show answer and solution

Answer: (d)

$Y = \overline{\bar{A} \cdot \bar{B}} = A + B$ , an OR gate.
So $Y$ is high whenever either $A$ or $B$ is high.
B is high during 0–7.5, 10–15 and 17.5–22.5, and every A pulse lies inside these intervals, so $Y$ follows these intervals.
So the answer is (d).
