Physics - Semiconductors Question with Solution | TestHub

The given circuit consists of an AND gate followed by a NAND gate.

Let the output of the first gate (AND gate) be $X$.
$X=A\cdot B$

The output of the second gate (NAND gate) is $Y$.
$Y=\overline{X\cdot C}=\overline{(A\cdot B)\cdot C}$

Case 1: When all inputs are zero ($A=0,B=0,C=0$)
$X=0\cdot 0=0$
$Y=\overline{0\cdot 0}=\overline{0}=1$

Case 2: When all inputs are one ($A=1,B=1,C=1$)
$X=1\cdot 1=1$
$Y=\overline{1\cdot 1}=\overline{1}=0$

Therefore, the output $Y$ is $1,0$.

Answer: 1,0
