AND gates
An AND gate, also called a Another name given to the AND gate., uses two inputs to generate one output. The output is 1 (TRUE) only if both of the inputs are 1 (TRUE).
AND gates are represented diagrammatically as:
A represents the first input. B represents the second input. Q represents the output.
A A table to list the output for all possible input combinations into a logic gate. shows, for each combination of inputs, what the output will be. An AND gate is represented in a truth table as seen below.
| A | B | Q |
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
| A | 0 |
|---|---|
| B | 0 |
| Q | 0 |
| A | 0 |

| B | 1 |
| Q | 0 |
| A | 1 |

| Q | 1 |
This AND gate is represented in A form of algebra which works only with two values, TRUE or FALSE. as one of:
- A AND B
- A /\ B
- A.B
