Nor Symbol ⊽
NOR, short for NOT-OR, is a logical operation that produces true (1) only when both of its inputs are false (0). It is a fundamental operation in digital logic circuits and is often used as a building block for designing complex logical functions and arithmetic circuits.
Definition
NOR is a binary operation that takes two inputs and returns true (1) only when both inputs are false (0). It is essentially the negation of the OR operation. NOR is often denoted by the symbol "⊽" or expressed as A NOR B, where A and B are the input values.
Representation in HTML
In HTML, the NOR symbol "⊽" can be represented using the HTML entity ⊩.
Truth Table
| A | B | A ⊽ B |
|---|---|---|
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |
Usage in Mathematics
NOR is a fundamental logical operation used in digital circuits for implementing other logic gates and designing complex systems. It is particularly valuable due to its ability to create universal gates, meaning any logical function can be constructed using NOR gates alone.
Example
For example, consider two binary numbers A = 1010 and B = 1101. The NOR operation A ⊽ B results in 0000, where all bits are 1 only when both A and B are 0.
Applications
NOR gates are widely used in digital electronics, including the design of CPUs, memory systems, and other digital circuits. Their versatility and importance in logic design make them a fundamental component of modern computing.
NOR, or NOT-OR, is a crucial logical operation with applications in digital logic circuits. Its ability to serve as a universal gate makes it a cornerstone in the design and implementation of complex electronic systems.
