WebHamming's (7,4) algorithm can correct any single-bit error, or detect all single-bit and two-bit errors. In other words, the minimal Hamming distance between any two correct codewords is 3, and received words can be correctly decoded if they are at a distance of at most one from the codeword that was transmitted by the sender. WebIn some situations, burst errors occur, where several successive bits are affected. Parity bit We can detect single errors with a parity bit. The parity bit is computed as the exclusive-OR (even parity) or exclusive-NOR (odd parity) of all of the other bits in the word. ... Calculating the Hamming Code; manga archive free manga
