WebMar 24, 2024 · Examining the file indicates that this is an implementation of a Hamming (7,4) code. This method uses 3 parity bits for every 4 bits of data. This allows the receiver of the information to correct upto 1 bit of data errors (bit flipped from 1 to 0 or the other way around). If there are more than 1 bit errors, this parity is insufficient.
