Vedclass · Answer

(A) The given circuit consists of two diodes connected in parallel with a common resistor connected to the ground. Let us analyze the truth table for this circuit:$A$$B$$C$$0$$0$$0$$0$$1$$1$$1$$0$$1$$1$$1$$1$$1$. When both inputs $A$ and $B$ are at low potential $(0)$,both diodes are reverse-biased (or non-conducting),so the output $C$ is at ground potential $(0)$.$2$. When either $A$ or $B$ is at high potential $(1)$,the corresponding diode becomes forward-biased and conducts,pulling the output $C$ to a high potential $(1)$.$3$. This behavior corresponds to the Boolean expression $C = A + B$,which is the characteristic operation of an $OR$ gate.

In the circuit below,$A$ and $B$ represent two inputs and $C$ represents the output.
