What happens to the output of a NOR gate when both inputs are high?

In digital logic, a NOR gate is a combination of an OR gate followed by a NOT gate. This means that the output of a NOR gate is true (high or 1) only when both of its inputs are false (low or 0). When both inputs are high (1), the OR condition is satisfied since at least one input is high. The NOT operation then inverts this result.

Therefore, with both inputs being high, the output of the NOR gate will be low (0). This fundamental behavior defines the logic of the NOR gate and is crucial in digital circuit design, as it impacts how various circuits are constructed and function. Understanding the truth table for NOR gates helps in predicting the output based on any combination of input states. Thus, when both inputs are high, the output indeed goes low.
