Physics - Semiconductors Question with Solution | TestHub

From the given logic circuit, the inputs B and C are connected to an OR gate, producing an output $B+C$.

This output and input A are connected to an AND gate. The final output Y is given by the Boolean expression:
$Y=A\cdot (B+C)$

We require the output $Y=1$. For an AND gate to output 1, both its inputs must be 1. This implies $A=1$ and $B+C=1$.

Evaluating the given options:
For $A=0,B=0,C=0$: $Y=0\cdot (0+0)=0$
For $A=0,B=1,C=0$: $Y=0\cdot (1+0)=0$
For $A=1,B=0,C=0$: $Y=1\cdot (0+0)=0$
For $A=1,B=0,C=1$: $Y=1\cdot (0+1)=1$

Thus, the input combination $1,0,1$ gives the output $Y=1$.

Answer: 1,0,1
