Gray codes are less error-prone for mechanical devices that involve making and breaking electrical circuits because they only change in one bit position at a time.
So, they are considered as the minimum error code.
Gray codes are very useful in the normal sequence of binary numbers generated by the hardware that may cause an error or ambiguity during the transition from one number to the next. So, the Gray code can eliminate this problem easily since only one bit changes its value during any transition between two numbers.
The gray code which is also known as the reflected binary code is a binary numeral system where two successive values differ in only one bit.Gray codes are mostly used to facilitate error correction in digital communication.
