In principle, there can be more than one such code for a given word length, but the term Gray code was first applied to a particular binary code for non-negative integers, the binary-reflected Gray code, or BRGC. Bell Labs researcher George R. Stibitz described such a code in a 1941 patent application, granted in 1943.

格雷碼（Gray code）是由貝爾實驗室的Frank Gray在1940年提出，用於在PCM（脈衝編碼調變）方法傳送訊號時防止出錯，並於1953年三月十七日取得美國專利。格雷碼是一個數列集合，相鄰兩數間只有一個位元改變，為無權數碼，且格雷碼的順序不是唯一的。

Sep 19, 2023 · A binary numbering system in which two successive values only differ by one bit is called gray code, often referred to as reflected binary code or unit distance code. Frank Gray created it in 1953, and today it is a common tool for error detection and repair in digital communication and data storage systems.

在一组数的编码中，若任意两个相邻的代码只有一位二进制数不同，则称这种编码为 格雷码 （Gray Code），另外由于最大数与最小数之间也仅一位数不同，即“首尾相连”，因此又称 循环码 或 反射码 。

Definition: Gray Code is the minimum-change code category of coding in which, the two consecutive values changes by only a single bit. More specifically we can say, it is a binary number system where while moving from one step to the next, only a single bit shows variation.

3.4 Gray Code: Comments •There are various codes that satisfy the Gray code feature. •Gray code saves communication power when the signals are continuous in nature, e.g. addresses, analog signals •Gray code facilitates code checking when the signals are supposed to be continuous in value. •For arithmetic operations, we need to convert ...

What is Gray code? (Definition, Conversions & Examples): This Gray code belongs to a class of codes called minimum-change code, in which only one bit in the code group changes when going from one step to the next. This is an unweighted code, which means that there are no specific weights assigned to the bit position. Because of this, the Gray ...

A Gray code is an encoding of numbers so that adjacent numbers have a single digit differing by 1. The term Gray code is often used to refer to a "reflected" code, or more specifically still, the binary reflected Gray code.

Jan 9, 2016 · In Graph Theory, snake-in-the-box codes (snakes) and coil-in-the-box codes (coils) are referred to as Gray Codes, because they detect single bit coding errors. In rotary systems, single-track Gray Codes (STGC) are used to sense contacts with rotary tracks.
