Abstract

Fremgangsmåte for overføring av kodede, digitale "bifase"-signaler, omfat- tende de trinn å motta ett av et flertall med inngangsdatabiter, hvor hver databit er kjennetegnet ved en tidsmessig databitlengde (12), et tidsmessig bitsenter (T3) og en tidsmessig tilstand som indikerer en logisk 1 eller O, og som genererer et kodet, digitalt basisbåndsignal som er kjennetegnet ved en tidsmessig tilstand som indi- kerer en logisk tilstand hvor det kodede, digitale basisbåndsignal endrer sin tids- messige tilstand i henhold til om den ene inngangsdatabrt endrer sin tidsmessige tilstand ved en tid før (T1 eller 6) eller etter (T2 eller 7) det tidsmessige bitsenter (T3). Et enkeltsidebånd med denne kodingen blir generert uavhengig ved hjelp av digital syntese. Deteksjon av enkeltsidebåndet krever ikke gjeninnsetting av bærebølgen.
