Vedclass · Answer

(C) Let us analyze each logic gate:$(a)$ This is a $NOR$ gate with inputs $1$ and $1$. The output of a $NOR$ gate is $Y = \overline{A+B}$. For inputs $1, 1$,$Y = \overline{1+1} = \overline{1} = 0$.$(b)$ This is a $NOR$ gate with inputs $0$ and $1$. For inputs $0, 1$,$Y = \overline{0+1} = \overline{1} = 0$.$(c)$ This is a $NAND$ gate with inputs $0$ and $1$. The output of a $NAND$ gate is $Y = \overline{A \cdot B}$. For inputs $0, 1$,$Y = \overline{0 \cdot 1} = \overline{0} = 1$.$(d)$ This is an $XOR$ gate with inputs $0$ and $0$. The output of an $XOR$ gate is $Y = A \oplus B$. For inputs $0, 0$,$Y = 0 \oplus 0 = 0$.Therefore,only gate $(c)$ has an output of $1$.
