What is the primary purpose of Gray Code?

The primary purpose of Gray Code is to change values with only one bit change. This encoding method is especially important in applications where errors during transitions between values could severely impact the system’s operation. For example, in rotary encoders and digital communication, using Gray Code minimizes the chance of misreading the value during a state change because only one bit toggles at a time. This property reduces the possibility of errors when transitioning between consecutive values, making Gray Code useful in various engineering and computer science applications.

In contrast, while representation of decimal numbers, character encoding, and numerical standardization are important concepts, they do not encapsulate the unique operational advantage that Gray Code offers in maintaining state integrity during transitions.
