NOR logic - Wikipedia
A NOR gate or a NOT OR gate is a logic gate which gives a positive output only when both inputs are negative. Like NAND gates , NOR gates are so-called " universal gates " that can be combined to form any other kind of logic gate .
或非门 - 维基百科，自由的百科全书
或非门（英語： NOR gate ）是数字逻辑中实现逻辑或非的逻辑门，功能见右侧真值表。若输入均为低电平（0），则输出为高电平（1）；若输入中至少有一个为高电平（1），则输出为低电平（0）。
逻辑或非 - 维基百科，自由的百科全书
在布尔逻辑运算中，逻辑或非（nor）的结果是逻辑或的反面。 也就是说， p NOR q 真，当且仅当 p 与 q 都假时才成立。 逻辑或非 是对于命题之间的运算，两个参数均假时结果才真；反之，两个参数中至少有一个为真时，结构就为假。
NOR Gate - Truth Table, Logic Diagram, Implementation, Solved …
2024年11月29日 · An XNOR gate, also known as an equivalence gate or an EX-NOR gate, is a digital logic gate that outputs true (1) when an even number of tr 10 min read OR Gate
NOR gate - Wikipedia
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. …
Logical NOR - Wikipedia
The NOR operation is a logical operation on two logical values, typically the values of two propositions, that produces a value of true if and only if both operands are false. In other words, it produces a value of false if and only if at least one operand is true.
Logic NOR Gate Tutorial with Logic NOR Gate Truth Table
2023年2月12日 · Logic NOR Gates are available using digital circuits to produce the desired logical function. It is given a symbol whose shape is that of a standard OR gate with a circle, sometimes called an “inversion bubble” at its output to represent the NOT (Inversion) gate symbol as …
NOR Gate | A Tutorial with the Truth Table and Use Cases
2023年6月12日 · A NOR Gate is a logic gate that has an output that is normally high (ON or 1), and goes low (OFF or 0) when ANY of its inputs are high. A) A simple way to think of the NOR Gate is by asking someone to put out their empty hands.
NOR -- from Wolfram MathWorld
4 天之前 · A predicate in logic equivalent to the composition NOT OR that yields false if any condition is true, and true if all conditions are false. A NOR B is equivalent to !(A v B), where !A denotes NOT and v denotes OR. In propositional calculus, the term joint denial is used to refer to the NOR connective.

2019年8月7日 · A single NOR gate. Like NAND gates, NOR gates are so-called "universal gates" that can be combined to form any other kind of logic gate. For example, the, Apollo Guidance Computer, was built exclusively from NOR gates, about 5,600 in total for the later versions. Today, contrary to popular belief, integrated circuits are not constructed ...
