Self complementing codes
WebFor example, 2421 is self-complementing: computing the 9-complement of a digit is the same as negating its bits. In textbooks you can find tables in which the authors choose one possible code for each digit, but this choice is arbitrary, and you might find different choices in different textbooks.

Now, assume a code with weights are W1,W2,W3 and W4. We want to prove that, W1 + W2 + W3 + W4 = 9 Let 'N' be a number in decimal. Let N's binary equivalent in given code be X1X2X3X4 Lets represent complement of N as COMP(N).
WebFor excess-3 codes, the invalid code groups are 0000, 0001, 0010, 1101, 1110 and 1111. The key feature of the excess-3 codes is that it is self-complementing code. It means that 1’s complement of the coded number yields 9’s complement of the number itself. WebWe would like to show you a description here but the site won’t allow us.
