Vedclass · Answer

(C) The given logic circuit consists of a $NOR$ gate followed by a $NOT$ gate (represented by the $NOR$ gate with shorted inputs). Let the output of the first $NOR$ gate be $Y' = \overline{A + B}$. This output $Y'$ is fed into a second $NOR$ gate whose inputs are shorted together,which acts as a $NOT$ gate. Thus,the final output is $Y = \overline{Y'} = \overline{\overline{A + B}} = A + B$. This is the Boolean expression for an $OR$ gate. The truth table for an $OR$ gate is given in option $C$.
