- AND Gate: The Logic AND Gate is a digital logic circuit whose output is 1 (HIGH) only when all the inputs are 1 (HIGH)
| A | B | C = A . B |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
- OR Gate: The Logic OR Gate is a digital logic circuit whose output goes HIGH to a logic level 1 only when one or more of its inputs are HIGH
| A | B | C = A + B |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
- NOT Gate: The Logic NOT Gate is the most basic of all the logic gates and is often referred to as an Inverting Buffer or simply an Inverter.
| A | B |
|---|---|
| 0 | 1 |
| 1 | 0 |
- NAND Gate: The logic Gate is obtained after adding NOT Gate after AND Gate.
- NOR Gate: The logic Gate is obtained after adding NOT Gate after OR Gate.
EXPLANATION:
- Since the output of OR Gate is input for both the inputs of NAND Gates, Both the inputs will be the same.
- When a NAND gate is connected to the same input it acts as a NOT Gate.
- The output of NAND Gate will be (same input)
- If NOT Gate is added after OR Gate, It will act as NOR Gate.
- So, The output of an OR gate is connected to both the inputs of a NAND gate. The combination will serve as NOR Gate. Hence the correct answer is option 4.
