Gray Codes
Author Joseph Malkevitch’s
Summary
The article “Gray Codes” from the American Mathematical Society’s Feature Column explains the fascinating mathematics behind a special way of arranging binary numbers so that consecutive values differ by only one bit. These Gray codes were developed to reduce errors in mechanical and electronic systems, especially in devices such as rotary encoders, where multiple bits changing simultaneously could create incorrect readings.
The article explores their history, construction methods, and applications in computer science, communication systems, error correction, puzzles, and digital technology. It also shows how a simple combinatorial idea connects abstract mathematics with practical engineering problems.
