OR gate
An OR logic gate takes two input signals and produces an output signal that is 1
if at least one of the input signals is 1.
In other words, as long as they are not both 0, the output will be 1.
Truth table
The truth table for it looks like:
| Input A | Input B | Output (A OR B) |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
