Question

The logic gate equivalent to the circuit shown in the figure is:

• A. AND
• B. NAND
• C. NOR
• D. OR

Hint:

The NAND gate is universally significant because it can be used to construct all other logic gates.

Answer 1

The Correct Option is B

Step 1: Identifying Gate Configuration From the given circuit diagram: - The circuit consists of a combination of AND gates followed by a NOT gate. - The standard logical operation for this setup results in a NAND gate, as it negates the output of an AND gate. Step 2: Boolean Representation For inputs \( A \) and \( B \): \[ \text{AND Gate: } Y = A \cdot B \] Applying the NOT gate: \[ \text{Final Output: } Z = \overline{A \cdot B} \] which represents the NAND operation. Conclusion Thus, the correct answer is: \[ \text{NAND} \]
