Gray Code

Definition - What does Gray Code mean?

Gray code evaluates the nature of binary code or data that is composed of on and off indicators, commonly represented by ones and zeros. Developed by Bell Labs scientists, gray code has been used to look at clarity and error correction in binary communications.

Gray code is also known as reflected binary code.

Techopedia explains Gray Code

Essentially, gray code works to sophisticate and clarify binary results. Part of this process deals with the idea of physical switches for binary code; experts explain that physical switches may not synchronize exactly. Other problems include signal noise, where misplaced binary bits or numbers could cause transmission problems.

To that end, gray code examines one switch or segment of binary at a time, and goes through binary code methodically to look for consistency. Some common examples are applications for digital terrestrial TV signals and cable-delivered digital signals.
