A 2-input NOR gate produces an output that is true (1) only when both of its inputs are false (0). Here is the truth table for a 2-input NOR gate:
| A | B | Output (A NOR B) |
|---|---|------------------|
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |
In summary, the output is `1` only when both inputs `A` and `B` are `0`. In all other cases, the output is `0`.
| A | B | Output (A NOR B) |
|---|---|------------------|
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |
In summary, the output is `1` only when both inputs `A` and `B` are `0`. In all other cases, the output is `0`.
