Gray code is useful because only one bit changes at a time. When used as encoders for a position sensor, for instance, if the sensor were right at the edge of a change boundary, there is uncertainty as to position. Binary code would introduce variable uncertainty in position, because more than one bit can change at a time, but gray code would reduce that uncertainty to being only one bit position in size.
Gray code is a 'reflected code', why is it named so will be illustrated soon. The advantage of Gray code over binary code is that only one bit in the code group changes when going from one number to the next. By, Ashish Kumar (Roh, Nawada, Bihar)
gray code is one which changes one bit at a time but binary code is one which changes one or more bit at a time. for example three bit binary and gray code the left one is binary and the right one is gray code.binary gray000 000001 001010 011011 010100 110101 111110 101111 100000 000

BCD refers to Binary Code Decimal there are no diagrams it is just a numbers system GRAY code is a means to make one reliable state to change at a time eliminating false coding because of transitions in counters and such
An absolute optical encoder is a type of rotary encoder. The optical disk is designed to produce a digital word which distinguishes N distinct positions of the shaft. Common types of numerical encoding used in the absolute encoder include gray and binary codes. http://www.motioncontrolguide.com/learn/guides/encoders-guide/
Gray code is primarily used in digital systems for position encoding and error correction. One application is in rotary encoders, where the Gray code allows for smooth and error-free transitions between positions, as only one bit changes at a time. Another application is in error detection for data transmission, where Gray code helps minimize errors during signal transitions, especially in noisy environments. Diagrams for these applications typically show the binary and corresponding Gray code representations, illustrating how adjacent values differ by only one bit.

characteristic of Gray code
Gray codes are used primarily to minimize errors in digital systems, particularly in applications involving rotary encoders and analog-to-digital conversions. Unlike binary codes, where multiple bits may change simultaneously, Gray codes ensure that only one bit changes at a time during transitions, reducing the likelihood of misreads or glitches. This property makes Gray codes particularly valuable in applications requiring precise position tracking and signal integrity. Additionally, they simplify certain circuit designs and improve reliability in various digital communication systems.
One disadvantage of Gray code is that it is not as intuitive for human understanding compared to binary code. Another drawback is that Gray code is not as efficient in terms of mathematical operations, such as addition and subtraction, compared to binary code. Additionally, Gray code requires more bits to represent the same range of values as binary code, which can result in increased complexity and storage requirements.
The Gray Code is a type of binary code developed by a programmer named Frank Gray. Gray code is a binary numeral system that differ than normal binary code, and is used widely to detect errors in software.
