An AND Gate is a logic gate in boolean algebra which results to 1 (True) if all the
|
|
inputs are 1 (True), and 0 (False) otherwise.
|
|
|
|
Following is the truth table of a Two Input AND Gate:
|
|
------------------------------
|
|
| Input 1 | Input 2 | Output |
|
|

|
|
| 0 | 0 | 0 |
|
|
| 0 | 1 | 0 |
|
|
| 1 | 0 | 0 |
|

| 1 | 1 | 1 |
