Many types of error-correcting techniques exist, but in data communications, Hamming encoding probably finds the widest use. Unlike serial-port communications that use a single parity bit, Hamming ...

Assume data bit 0, the first data bit, is incorrect. Because bit 0 is incorrect the bits 1, 3, 4, and 5 (lines 1 and 4 equations) may be calculated as incorrect. But the calculation of those bits ...

Second, the codes are typically 7 or 8 bits, which makes for an inefficient use of a 16-bit memory structure. This is handled by using the same memory chip for data and codes. This is referred to as ...
