Physics - Semiconductors Question with Solution | TestHub

From the given logic circuit, the gates can be identified as follows:
1. A NOT gate with input $A$, giving output $\bar{A}$.
2. An AND gate with inputs $B$ and $C$, giving output $B\cdot C$.
3. An OR gate taking the outputs of the NOT and AND gates as inputs.

The Boolean expression for the final output $Y$ is:
$Y=\bar{A}+B\cdot C$

For the output to be $Y=1$, either $\bar{A}=1$ (which means $A=0$) or $B\cdot C=1$ (which means $B=1$ and $C=1$).

Since all given options have $A=1$, we have $\bar{A}=0$.
Thus, for $Y=1$, the condition $B\cdot C=1$ must be satisfied, which requires $B=1$ and $C=1$.

Therefore, the correct input combination is $A=1$, $B=1$, $C=1$.

Answer: $A=1$ , $B=1$ , $C=1$
