Gray Code是一个数列集合,每个数使用二进位来表示,假设使用n位元来表示每个数好了,任两个数之间只有一个位元值不同,例如以下为3位元的Gray Code:
000 001 011 010 110 111 101 100
由定义可以知道,Gray Code的顺序并不是唯一的,例如将上面的数列反过来写,也是一组Gray Code:
100 101 111 110 010 011 001 000
Gray Code是由贝尔实验室的Frank Gray在1940年代提出的,用来在使用PCM(Pusle Code Modulation)方法传送讯号时避免出错,并于1953年三月十七日取得美国专利。-Gray Code is a series set, each binary number to represent, assuming the number of n bits to represent each well, and any number between two values is only a bit different, such as the following 3-bit Gray Code: 000 001 011 010 110 111 101 100 from the definition that, Gray Code sequence is not unique, for example, to write the above series, in turn, is a Gray Code: 100 101 111 110 010 011 001 000 Gray Code by Frank Gray of Bell Labs made in the 1940s, to the use of PCM (Pusle Code Modulation) method to send signals to avoid mistakes, and in March 17, 1953 to obtain U.S. patents.
