Boolean logic
Logic gate symbols
- Six different logic gates will be considered in this chapter.

- Truth tables are used to trace the output from a logic gate or logic circuit.
- The NOT gate is the only logic gate with one input; the other five gates have two inputs.
| Input | Input | Output |
|---|---|---|
| A | B | X |
| 0 | 0 | 0 |
| 0 | 1 | 0 |
