WebFor example, assume the codeword is corrupted to give 1010 0000 1010. Check parity: Bit 1: B1 B3 B5 B7 B9 = 1 1 0 0 1 = 1 Bit 2: B2 B3 B6 B7 B10 = 0 1 0 0 0 = 1 Bit 4: B4 B5 … WebThe Hamming distance between two equal-length strings of symbols is the number of positions at which the corresponding symbols are different. Examples. The symbols may be letters, bits, or decimal digits, among other possibilities. For example, the Hamming distance between: "ka rol in" and "ka thr in" is 3. "k a r ol in" and "k e r st in" is 3.
