Why to use Gray codes?

Gray codes are used primarily to minimize errors in digital systems, particularly in applications involving rotary encoders and analog-to-digital conversions. Unlike binary codes, where multiple bits may change simultaneously, Gray codes ensure that only one bit changes at a time during transitions, reducing the likelihood of misreads or glitches. This property makes Gray codes particularly valuable in applications requiring precise position tracking and signal integrity. Additionally, they simplify certain circuit designs and improve reliability in various digital communication systems.
