Vedclass · Answer

(B) For figure $(a)$: The gate is an $OR$ gate with inverted inputs. The output $Y = \bar{A} + \bar{B}$. According to De Morgan's theorem,$\bar{A} + \bar{B} = \overline{A \cdot B}$. This is the Boolean expression for a $NAND$ gate.For figure $(b)$: The gate is an $AND$ gate with inverted inputs. The output $Y = \bar{A} \cdot \bar{B}$. According to De Morgan's theorem,$\bar{A} \cdot \bar{B} = \overline{A + B}$. This is the Boolean expression for a $NOR$ gate.Therefore,$(a)$ is equivalent to a $NAND$ gate and $(b)$ is equivalent to a $NOR$ gate.
