Weighted codes assign different significance to each digit in a number representation, such as 8421 BCD code assigns weights of 8, 4, 2, and 1 respectively to each bit. In contrast, non-weighted codes like Gray code do not follow a positional weight pattern, where only one bit changes at a time when moving from one value to another to reduce errors in analog-to-digital conversion systems.
Weighted codes have there bits presented in weightage. Simply put weighted codes are codes used for arithmetic operation. And unweighted codes there are no values for the bits. Simply put they can not be used for calculations. Examples are 8421 (BCD) binary, hex, octal ETC. For the former And grey codes, excess-3 etc. For the later.
It is a non-weighted code, that is, each position of its bit isn't assigned a particular value.
weighted
what is weighted codes: The decimal value of a code is obtained summing up the positional values. weghted binary code s are those which obey positional weighting principle. each position of number represents a specific weight. There are millions of weighted code The most common one is 8421 Non weighted codes: This codes are not positionaly weghted. each position with in the binary no is not assgned to afixed value.Examples of nonweghted code is ASCCI, GREY CODE, EBCDIC CODE etc

Gray codes can be used in some cases of clock domain crossing. For gray codes to be useful for clock domain crossing, the following condition must be met: gray code must encode a counter or decounter (one value and the next must have a constant distance of 1) Because of this condition, the most common use case for gray codes is for encoding the pointers of an asynchronous FIFO. In related domains, gray codes can also be used in telecommunications in order to minimize the impact of analog noise on a digital communication.
It is that type of binary code where weights are assigned to each symbol position in the code word.

codes that can no longer be used
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.
Waited is the homophone of weighted.
