Checksum counter
WebIn order to detect any single bit-error, an additional safeguard is necessary: the 3-bit stuff-bit counter (SBC). The gray-coded SBC is protected by a parity bit and the following fixed stuff-bit is so-to-speak a second parity bit, because the fixed stuff-bits always have the opposite value of the previous bit. A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage. By themselves, checksums are often used to verify data integrity but are not relied upon to verify data authenticity. The procedure which generates this checksum is called a checksum function or checksum …
