NOR Gate — UniversalHardQuestion 20254
Question
To implement a NOT gate using NOR gates, one would:
- AConnect two NOR gates in series
- BConnect both inputs of a NOR gate togetherCorrect
- CUse one NOR gate with inputs at opposite values
- DIt cannot be done with NOR alone
Correct answer
Connect both inputs of a NOR gate together
Explanation
NOR with both inputs tied to A: Y = (A+A)̄ = Ā. Like NAND, NOR is a universal gate. Any digital function can be built using only NOR gates.
