error detecting code

Parity bits are used as the simplest form of error detecting code.

In information theory, a parity bit appended to a binary number provides the simplest form of error detecting code.

Error detecting codes can be optimised to detect burst errors, or random errors.

However, for safety-critical systems, simple error detecting codes, such as CRCs, provide the same or better coverage at a much lower cost.

Like all unidirectional error detecting codes, Berger codes can also be used in delay-insensitive circuits.

Be familiar with the classical Hamming and BCH error detecting codes.

The DSC is a synchronous system using characters composed from a ten-bit error detecting code.

While error detecting codes, such as CRCs, are better than cryptographic techniques, neither provide adequate coverage for active electronics in safety-critical systems.

Some more sophisticated error detecting codes are also based on the use of multiple parity bits for subsets of the bits of the original encoded value.

In telecommunication, a Berger code is a unidirectional error detecting code, named after its inventor, J. M. Berger.

The EDC/ECC technique uses an error detecting code (EDC) in the level 1 cache.

Data is encoded using 7 unit binary codes sent using a seven bit error detecting code called van Duuren code or CCITT Telegraph Alphabet No. 3.

It has also been proved that if the number of frequencies is a prime or a power of a prime, the orthogonal Latin squares produce error detecting codes that are as efficient as possible.

Finally, some transport layer protocols, for example TCP, but not UDP, provide end-to-end reliable communication, i.e. error recovery by means of error detecting code and automatic repeat request (ARQ) protocol.
