Grey code, also known as reflected binary code, is a binary numeral system where two consecutive values differ in only one bit position. In other words, each bit position represents a power of two, and each number in the sequence differs from its neighbor by only one bit.

USE CASES :

The Grey code is useful in a variety of applications, such as in digital communication systems, in precision measurement devices, and in robotics. One of the main advantages of the Grey code is that it eliminates the possibility of errors due to multiple bits changing simultaneously during transitions, as only one bit changes at a time. This property makes it particularly useful in mechanical devices where there may be noise or interference.

For example, in a shaft encoder, which is used to determine the position of a rotating shaft, the use of Grey code can help ensure that the encoder outputs a reliable signal even in noisy environments. Similarly, in robotics, Grey code is often used to encode the position of a robot joint or end effector, where precise and reliable position feedback is crucial.

In digital communication systems, Grey code can be used to minimize the number of bit errors that occur during transmission, especially in situations where data is transmitted over an unreliable or noisy channel. By using Grey code, it is possible to reduce the number of bit errors that occur during transmission, thereby increasing the reliability of the system.
