Vedclass · Answer

(B) The given circuit consists of two $NOT$ gates connected to the inputs $A$ and $B$, followed by a $NOR$ gate.$1$. The outputs of the two $NOT$ gates are $\overline{A}$ and $\overline{B}$.$2$. These are fed as inputs to a $NOR$ gate.$3$. The output $Y$ of the $NOR$ gate is given by $Y = \overline{\overline{A} + \overline{B}}$.$4$. Using De Morgan's theorem, $\overline{\overline{A} + \overline{B}} = \overline{\overline{A}} \cdot \overline{\overline{B}} = A \cdot B$.$5$. The expression $A \cdot B$ represents the operation of an $AND$ gate.Therefore, the combination represents an $AND$ gate.

Input $A$	Input $B$	Output $Y$
$0$	$0$	$1$
$0$	$1$	$1$
$1$	$0$	$1$
$1$	$1$	$0$
