Physics - Semiconductors Question with Solution | TestHub

From the given logic circuit diagram:

The inputs to the upper AND gate are $A$ and $\bar{B}$ (from the NOT gate connected to $B$). Thus, the output of the upper AND gate is $A\bar{B}$.

The inputs to the lower AND gate are $\bar{A}$ (from the NOT gate connected to $A$) and $B$. Thus, the output of the lower AND gate is $\bar{A}B$.

These two outputs are fed into an OR gate. The final output $Y$ is the logical sum of these inputs:

$Y=A\bar{B}+\bar{A}B$

This is the standard Boolean expression for an Exclusive-OR (XOR) gate.

Answer: XOR gate
