GERBANG LOGIKA
v Gerbang AND
Outputnya akan bernilai “1”,jika kedua inputnya “1”.
| A | B | Q |
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
v Gerbang OR
Outputnya akan bernilai “1” jika salah satu inputnya bernilai “1”
| A | B | Q |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
v Gerbang NOT (INVERTER)
Output akan selalu berlawanan dengan inputnya
| A | B |
| 0 | 1 |
| 1 | 0 |
v Gerbang NAND (Not AND)
Output akan bernilai “0” jika kedua inputnya “1”
| A | B | Q |
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
v Gerbang NOR
Outputnya akan bernilai “1” jika kedua inputnya bernilai “0”
| A | B | Q |
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |
v Gerbang XOR (Exclusive OR)
Outputnya akn bernilai “1” jika inputnya berbeda
| A | B | Q |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
| A | B | Ā |  B | Ā.B |  A.B |  Ā.B + A.B |
| 0 | 0 | 1 | 1 | 0 | 0 | 0 |
| 0 | 1 | 1 | 0 | 1 | 0 | 1 |
| 1 | 0 | 0 | 1 | 0 | 1 | 1 |
| 1 | 1 | 0 | 0 | 0 | 0 | 0 |
v Gerbang XNOR (Exclusive NOR)
Outputnya akan bernilai “1” jika inputnya sama
| A | B | Q |
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
