When does the output of a NOR gate =0?
- whenever 0 is present at input
- only when all input =0
-
whenever 1 is present at input
- only when all input =1.
The correct answer is: C
Explanation
The NOR gate is a digital logic gate that implements logical NOR - it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results.
