Question
Name the logic gate which can be realised by using a p-n junction diode in the given diagram. Give its logic symbol and write the truth table. Name the gate which will be obtained by combining with a NOT gate.
✓
Answer
The logic gate shown in the circuit diagram is OR gate.
Symbol of OR gate:
The gate obtained by combining OR gate with NOT gate will be NOR gate.
Symbol of OR gate:
| Input | | Output |
| A | B | Y |
| 0 | 0 | 1 |
| 1 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 1 | 1 |
