Question

The output Y for the inputs A and B of the given logic circuit is :

• A. A ⋅ B
• B. $\bar{A}\cdot \bar{B}$
• C. A + B
• D. $\bar{A} + \bar{B}$

Answer 1

Answer: (C)

A + B

Answer 2

The circuit consists of two OR gates whose outputs are then applied as inputs to another OR gate. Therefore, the logic expression for the output Y is:
Y = (A + B)
