Question

Choose the correct logic circuit for the given truth table having inputs A and B.

• A.
• B.
• C.
• D.

Hint:

Analyze each logic gate combination and compare its output with the given truth table to find the correct match.

Answer 1

The Correct Option is B

The truth table shows that the output Y is 1 only when either A is 1 and B is 0, or both A and B are 1. 
This can be represented as Y = (A AND NOT B) OR (A AND B).
Logic circuit (2) contains an AND gate, and an OR gate, and a NOT gate which matches to the truth table.
So the answer is (2).
