Answer – The NOR gate produces a high output (1) only when both of its inputs are low (0). If either or both inputs are high (1), the output is low (0).
Explanation:
A NOR gate is a digital logic gate that performs the NOR operation, which is a combination of the NOT and OR operations. The NOT operation takes a single input and produces its negation, while the OR operation takes two inputs and returns true if at least one of them is true; otherwise, it returns false.
The truth table for a NOR gate is as follows:
| A | B | A NOR B |
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |
The NOR gate typically has two inputs, often labeled as input A and input B. These inputs can take binary values of 0 or 1. The output is 1 (true) only when both inputs A and B are 0 (false). In all other cases (when at least one of the inputs is 1), the output is 0 (false).
In practical applications, NOR gates are commonly used to build digital circuits, including memory units, flip-flops, and more complex logic circuits.
