An OR gate is a fundamental digital logic gate that implements logical disjunction. It produces a true output (1) if at least one of its inputs is true (1). The OR gate is widely used in digital circuits, computer systems, and other electronic devices for decision-making processes.
OR Gate Truth Table
The truth table for an OR gate shows the relationship between the input values and the corresponding output value. Here is the truth table for a 2-input OR gate:
| Input A | Input B | Output (A ∨ B) ||---------|---------|----------------|| 0 | 0 | 0 || 0 | 1 | 1 || 1 | 0 | 1 || 1 | 1 | 1 |In this table:
0 represents a false value.
1 represents a true value.
The output is true if at least one of the inputs is true.
Multi-Input OR Gate
An OR gate can have more than two inputs. For example, a 3-input OR gate will have the following truth table:
