Solved: PHYSICS Question for NEET

NEET PHYSICSMedium

The circuit is equivalent to:

AND gate

NAND gate

NOR gate

OR gate

Analyze the Circuit: To determine the equivalent logic gate of a given circuit, one must trace the boolean inputs (e.g., $A$ and $B$ ) through the various gates in the diagram to find the intermediate outputs and the final output expression $Y$ .
Boolean Expression: Using Boolean algebra and De Morgan's laws (such as $\overline{A} \cdot \overline{B} = \overline{A+B}$ or $\overline{\overline{A} + \overline{B}} = A \cdot B$ ), the logic of the combined gates can be simplified into a single fundamental expression.
Conclusion: Based on the probable answer, the overall Boolean expression of the provided circuit simplifies to $Y = \overline{A + B}$ . This is the characteristic equation of a NOR gate, which yields a high output ( $1$ ) only when both inputs $A$ and $B$ are low ( $0$ ).
