What is Gray Code? and Gray Code's Advantages

Gray code is not suited for arithmetic operations but finds applications is input/output devices and some types of analog to digital converters (ADCs)

This code belongs to a class of codes called minimum change code in which only one bit in the code group changes when going from one step to the next. This is an un-weighted code which means that there are no specific weights assigned to the bit positions.

Because of this the Gray code is not suited for arithmetic operations but finds applications is input/output devices and some types of analog to digital converters (ADCs)

Advantages of Gray Code

In Gray code, if we go from one decimal number to next, only one bit of the gray code changes. Because of this feature, an amount of switching is minimized and the reliability of the switching systems is improved.
