Question

The above combination of logic gates represents the operation 

• A. OR
• B. NAND
• C. AND
• D. NOR

Hint:

A NAND gate is an AND gate followed by a NOT gate (inverter).

Answer 1

The Correct Option is B

The given combination of logic gates is two NOT gates followed by an AND gate.

Step 1: The two NOT gates invert the inputs before the AND gate processes them. This operation corresponds to a NAND gate.

Step 2: The combination of NOT and AND gates forms the NAND operation, which is the opposite of an AND gate.
Thus, the correct answer is (B).
