Types of logic gates
1.) OR gate
| A | B | Y = A+B |
| 0 | 0 | 0 |
| 1 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 1 | 1 |
When any of the inputs is high, the output is always high.
When all the inputs are low, then only the output is low.
2.) AND Gate
| A | B | Y = AB |
| 0 | 0 | 0 |
| 1 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 1 | 1 |
When any of the inputs is low, the output is always low.
When all the inputs are high, then only the output is high.
3.) NOR Gate
| A | B | Y =\(\overline{A+B}\) |
| 0 | 0 | 1 |
| 1 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 1 | 0 |
When any of the inputs is high, the output is always low.
When all the inputs are low, then only the output is high.
4.) NAND Gate
| A | B | Y = \(\overline{AB}\) |
| 0 | 0 | 1 |
| 1 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 1 | 0 |
When any of the inputs is low, the output is always high.
When all the inputs are high, then only the output is low.
