Abstract

På inngangene til apparater til overføring eller behandling av digitalsignaler må disses takt gjenvinnes. En ny fremgangsmåte skaffer anordninger for dette og lar seg i størst mulig utstrekning^ realisere med logikkretser i form av %r portmatriser eller cellematriser. I en hjelpetaktgenerator (6) genereres en hjelpetakt eller en av denne utledet hjelpetakt (HT1,HT2) med samme frekvens, men med forskjellig fasestllling som ført over en fasekorreksjonslnnretning (7) gir en datahjelpetakt som gjenvunnet takt. Denne hjelpetakt eller hjelpetakt- ene (HT1,HT2) avviker prinsipielt med hensyn til sin frekvens fra den data- hjelpetakt (DHT) som skal geneireres. En fasesensor (1) tester om de virksonune flanker av digitalsignalet (DS) og data- hjelpetakten (DHT) nærmer seg til under en definert tidsavstand og avgir så snart dette er tilfelle et korreksjons- signal (K). Dette gjør at det i fase- korreksjonsinnretningen (7) skjer en faseforskyvning av datahjelpetakten (DHT) ved omkobling mellom de utledede hjelpetakter (HTl,HT2) og/eller ved om- polarisering av hjelpetakten eller de avledede hjelpetakter (HTl,HT2). Fremgangsmåten kan benyttes i digital-signal-multipleksapparater og -fordeler-multipleksere.
