Physics - Semiconductors Question with Solution | TestHub

Let inputs $A,B$ and $C$ are given to the circuit. Gate-I is AND gate while gate-II is NAND gate. Output $Y=\overline{(A.B.C)}$ When $A=1,B=1,C=1$, then $Y=\overline{(1\cdot 1)\cdot 1}=\overline{1\cdot 1}=\overline{1}=0$ When $A=0,B=0,C=0$, then $Y=\overline{(0.0)\cdot 0}=\overline{0.0}=1$
