To find out custom hamming code generator (SECDED) used in the example given in the word document .43 bits of bonary code contaians data bits represented by Bits 43 to 7 and parity bits 6 to 0, generated using custom algorithm to generate hamming code (SECDED) (Single error correction double error detection). The data bits represent 11 decimal digits. I am interested in finding the algorithm used in generation of parity bits. I have tried the standard hamming code algorithm but it doesn’t fit. It could be possible that In the above given examples both odd and even parity schemes were used.
