Logical NOR Gate NOR (NOT-OR) logic gate. Output 1 only if both inputs are 0. Truth table
Result
Logical NOR Gate NOR (NOT-OR) logic gate. Output 1 only if both inputs are 0. Truth table: 0,0→1 | 0,1→0 | 1,0→0 | 1,1→0. Used in digital circuits. — free online calculator.
Formula
- Logical NOR Gate NOR (NOT-OR) logic gate. Output 1 only if both inputs are 0. Truth table calculates its result from A (0 or 1), B (0 or 1). It uses the formula NOR = NOT(A OR B) = !(A | B). Change any input to recalculate the result instantly.
- The main inputs are A, B. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Logical NOR Gate NOR (NOT-OR) logic gate. Output 1 only if both inputs are 0. Truth table
- A: 0 0 or 1
- B: 0 0 or 1
Using A (0 or 1) = 0, B (0 or 1) = 0, the calculated result is 1.
