Question

Identify the logic operation performed by the following circuit. 
 

• A. OR
• B. AND
• C. NOT
• D. NAND

Hint:

Logic circuits can be reduced systematically using Boolean algebra to identify their equivalent gates.

Answer 1

The Correct Option is B

Step 1: {Circuit Description}
The logic circuit comprises two NOR gates feeding into a third NOR gate.
Step 2: {Boolean Derivation}
Applying De-Morgan’s theorem yields:
\[ Y = \overline{\overline{A} + \overline{B}} \]
\[ = A \cdot B \]
Step 3: {Result}
This circuit functions as an AND gate. Consequently, the correct option is (B).
