Betrachten wir uns nochmal die Wahrheitstabellen der Grundgatter AND und OR:
| E1 | E2 | A |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
| E1 | E2 | A |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
Fassen wir die Tabellen nun zusammen:
| E1 | E2 | A | A |
|---|---|---|---|
| 0 | 0 | 0 | 0 |
| 0 | 1 | 0 | 1 |
| 1 | 0 | 0 | 1 |
| 1 | 1 | 1 | 1 |
| A N D |
O R |
Im nächsten Schritt ergänzen wir auch noch NOR und NAND
| E1 | E2 | A | A | A | A |
|---|---|---|---|---|---|
| 0 | 0 | 1 | 1 | 0 | 0 |
| 0 | 1 | 0 | 1 | 0 | 1 |
| 1 | 0 | 0 | 1 | 0 | 1 |
| 1 | 1 | 0 | 0 | 1 | 1 |
| N A N D |
N O R |
A N D |
O R |
Was wir auch noch eintragen können sind A=E1 und A=E2
| E1 | E2 | A | A | A | A | A | A |
|---|---|---|---|---|---|---|---|
| 0 | 0 | 1 | 1 | 0 | 0 | 0 | 0 |
| 0 | 1 | 0 | 1 | 0 | 1 | 0 | 1 |
| 1 | 0 | 0 | 1 | 0 | 0 | 1 | 1 |
