Write the truth table for the circuit shown in the figure. Name the gate that the circuit resembles.

(N/A) The given circuit is an $OR$ gate.
When input $A$ or input $B$ is at a low potential $(0)$,the corresponding diode ($D_1$ or $D_2$) becomes forward-biased and conducts,pulling the output $V_0$ to a low potential $(0)$.
When both inputs $A$ and $B$ are at a high potential $(1)$,both diodes are reverse-biased and do not conduct. The output $V_0$ is then pulled to the high potential $(+5 \text{ V})$ through the resistor.
Thus,the circuit acts as an $OR$ gate.
The truth table is as follows:
| $A$ | $B$ | $V_0 = A + B$ |
|---|---|---|
| $0$ | $0$ | $0$ |
| $0$ | $1$ | $1$ |
| $1$ | $0$ | $1$ |
| $1$ | $1$ | $1$ |
