    Hi,
    I want to know why there is requirement to represent digital value in different binary code such as excess-3, grey code, 8421 code etc. Wether we require these codes for some particular application?

    Because some codes work efficiently than others at some applications.

    Grey code is useful as only 1 bit changes at a time (assuming linear change) so if you detect 2 bits have changed then you know you have an error. Often used for positional encoding on shafts (I believe)
