Vedclass · Answer

(C) Let $1$ represent the $ON$ state and $0$ represent the $OFF$ state.For a switch $S$, $S'$ represents the complement ($NOT$ gate).The circuit is represented by the Boolean expression: $L = (S_1 \land S_2) \lor (S'_1 \land S'_2)$.This is the $XNOR$ gate logic.The output $L$ is $1$ (lit) if both inputs $S_1$ and $S_2$ are the same.Therefore, the room is lit when $S_1$ and $S_2$ are both $ON$ $(1, 1)$ or both $OFF$ $(0, 0)$.

In a switching circuit, if the combination $(S_1 \land S_2)$ is connected in parallel to the combination $(S'_1 \land S'_2)$, then the room is lit only when ...
