The Gray code uses bits 0 and 1 to represent a value. But the Gray code is different from other binary codes in that the two successive values of numbers differ in only one bit – as we move from one number to another, e.g. decimal number 7 to decimal number 8, the Gray code will change in only one bit. So there is a change in only one bit as we move from one decimal number to the next. This simplifies hardware circuits. In this video tutorial, we learn how to convert a Gray code to its equivalent Binary code.
