Computer Science for IGCSE & O level - Boolean Logic (Section 8 - No. 1)
Which of the following statements is correct regarding the behavior of a NOR gate?
Output is high only if all inputs are low.
Output is low if any input is high.
Output is the inverse of the OR gate output.
Output is low only if all inputs are low.
Paliwanag
The output of a NOR gate is the inverse of the output of an OR gate. Meaning it will output 1 (high) if and only if all of its inputs are 0 (low).
