Question

The output (Y) of the given logic gate is similar to the output of an/a :

• A. NAND gate
• B. NOR gate
• C. OR gate
• D. AND gate

Answer 1

The Correct Option is D

To analyze the given circuit, let's break it step-by-step:
1. The circuit consists of two logic gates connected to form the output Y.
2. The input signals A and B are passed through an OR gate, producing $A + B$.
3. The output of the OR gate is then inverted (NOT gate), resulting in $\overline{A + B}$.
4. Finally, $\overline{A + B}$ is passed through another OR gate with the input $A \cdot B$, which gives:
$Y = (A \cdot B) \cdot (\overline{A + B})$.
The resulting operation is equivalent to the output of an AND gate.
