Correct option is C
The given truth table represents the
NAND (NOT AND) gate. Let's analyze the truth table:
| A |
B |
Output |
| 0 |
0 |
1 |
| 0 |
1 |
1 |
| 1 |
0 |
1 |
| 1 |
1 |
0 |
Important Key Points:
1. NAND Gate: The output is 1 for all combinations of inputs except when both are 1. The NAND gate performs the negation of the AND operation.
2. Truth Table for NAND:
· When A = 0 and B = 0: Output = 1
· When A = 0 and B = 1: Output = 1
· When A = 1 and B = 0: Output = 1
· When A = 1 and B = 1: Output = 0
Knowledge Booster:
· Option (a): XOR: The XOR (Exclusive OR) gate gives output 1 when exactly one of the inputs is 1, but this truth table does not match the XOR behavior.
· Option (b): NOR: The NOR gate gives output 1 only when both inputs are 0. This truth table does not match that behavior.
· Option (d): OR: The OR gate gives output 1 when at least one input is 1. This truth table differs from the behavior of the OR gate.
