What is Gray code?
A code in which successive values differ in only one bit. It prevents read errors in rotary encoders and when passing counter values between different clock domains.
Field: Logic circuits
Gray code in the explanations
Gray code changes exactly one bit between adjacent values and can be computed from binary B as B XOR (B >> 1).
Which is a characteristic of Gray code?Assigning bit patterns in Gray code, so adjacent states differ by one bit, limits each misread to a single-bit error and minimizes the ECC burden.
