प्रश्न
Two car garages have a common gate which needs to open automatically when a car enters either of the garages or cars enter both. Devise a circuit that resembles this situation using diodes for this situation.
उत्तर
As the car enters either of the garages or both, the common gate opened automatically. This means that if any one input is high, the output will be high otherwise low.
The device is shown like this:
So, OR gate gives the desired output.
| A | B | Y = A + B |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
