Abstract

Den foreliggende oppfinnelse omhandler en anordning for etablering av avgrensninger i en bitstrøm, som omformer et førte antall biter av bitstrømmen til et andre antall biter (dvs. CRC bestemmes), og sammen- ligner det andre antall biter med et tredje antall biter av bitstrømmen. Omformingsorganene omfatter fradragsorganer for reduksjon av virkningen av sam- menligningsprosessen med minst en bit plassert uten- for det første antall biter. Anordningen etablerer avgrensningen av bitstrømmen etter et minimalt tids- forløp, selv for svært høye bithastigheter pr. bit- skift.
