MCQ

In the given circuit, if $A$ and $B$ represent two inputs and $C$ represents the output, the circuit represents:

A
$\text{NOR}$ gate
B
$\text{AND}$ gate
C
Gate
✓
$\text{OR}$ gate

✓

Answer

Correct option: D.

$\text{OR}$ gate

The image given shows a diode $\text{OR}$ circuit. $R$ is connected from the output to ground to provide bias current for the diodes. Any positive voltage will represent a logic $1$ state and the summing of currents through multiple diodes does not change the logic level.
