Vedclass · Answer

(C) The circuit consists of a $NOR$ gate followed by a $NOR$ gate acting as a $NOT$ gate (since both inputs are tied together).Let the output of the first $NOR$ gate be $Y^{\prime} = \overline{A + B}$.The second gate is a $NOR$ gate with both inputs as $Y^{\prime}$,so its output is $Y = \overline{Y^{\prime} + Y^{\prime}} = \overline{Y^{\prime}} = \overline{\overline{A + B}} = A + B$.This is the Boolean expression for an $OR$ gate.The truth table for $Y = A + B$ is:$A$$B$$Y$$0$$0$$0$$0$$1$$1$$1$$0$$1$$1$$1$$1$Comparing this with the given options,option $C$ is correct.

In the following circuit,the output $Y$ for all possible inputs $A$ and $B$ is expressed by the truth table.
