What is Gray Code?
The binary numeral system is ordered in the reflected binary code, also known as the Gray code, so that two subsequent values only differ in one bit (binary digit). In the typical sequence of binary numbers produced by the hardware that could provide an error or ambiguity during the change from one number to the next, gray codes are highly helpful.
Because the first (n/2) values compare with the last (n/2) values in reverse order, gray code is also known as reflected binary code.
What is Gray Code?
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. The Gray code is a sequencing of the binary numeral system in which two successive values differ in an only binary digits.
