A XOR Gate is a logic gate in boolean algebra which results to 1 (True) if only one of
|
|
the two inputs is 1, and 0 (False) if an even number of inputs are 1.
|
|
Following is the truth table of a XOR Gate:
|
|
------------------------------
|
|
| Input 1 | Input 2 | Output |
|
|
------------------------------
|
|
| 0 | 0 | 0 |
|
|
| 0 | 1 | 1 |
|
|
| 1 | 0 | 1 |
|
|
| 1 | 1 | 0 |
