Vedclass · Answer

(B) In the given circuit,the switches $A_1$ and $B_1$ are connected in parallel. The output $Y$ is taken across the resistor connected to the ground.When both switches $A_1$ and $B_1$ are open (logic $0$),the output $Y$ is connected to $+5 	ext{V}$ (logic $1$).When either $A_1$ or $B_1$ is closed (logic $1$),the output $Y$ remains connected to $+5 	ext{V}$ (logic $1$).When both switches $A_1$ and $B_1$ are closed (logic $1$),the circuit is shorted to ground,and the output $Y$ becomes $0 	ext{V}$ (logic $0$).The truth table is:| $A_1$ | $B_1$ | $Y$ ||---|---|---|| $0$ | $0$ | $1$ || $0$ | $1$ | $1$ || $1$ | $0$ | $1$ || $1$ | $1$ | $0$ |This truth table corresponds to the $NAND$ gate,where $Y = \overline{A_1 \cdot B_1}$.
