उत्तर
(i) P and Q are the NOT and OR gates respectively. The truth table for them is drawn below:
| NOT | OR | |||
|---|---|---|---|---|
| Input | Output | Input 1 | Input 2 | Output |
| 1 | 0 | 1 | 1 | 1 |
| 0 | 1 | 0 | 0 | 0 |
| 1 | 0 | 1 | ||
| 0 | 1 | 1 | ||
(ii) The truth table for the whole network:
| Input -A | Input -B | Output |
|---|---|---|
| 1 | 1 | 1 |
| 0 | 0 | 1 |
| 1 | 0 | 0 |
| 0 | 1 | 1 |
