Vedclass · Answer

(B) The given circuit consists of two $NAND$ gates connected in series,where the second $NAND$ gate acts as a $NOT$ gate because its inputs are shorted together.Let the inputs to the first $NAND$ gate be $A$ and $B$. The output of the first $NAND$ gate is $\overline{A \cdot B}$.This output is fed as the input to the second $NAND$ gate. Since both inputs of the second $NAND$ gate are connected to the same signal,its output $Y$ is given by:$Y = \overline{(\overline{A \cdot B}) \cdot (\overline{A \cdot B})}$Using the property of Boolean algebra $\overline{X \cdot X} = \overline{X}$,we get:$Y = \overline{(\overline{A \cdot B})} = A \cdot B$Thus,the circuit performs the operation of an $AND$ gate.
