Abstract

En koblingsanordning har en fasekom-parator (Ph, FT1, FT2) som sammenligner referansetaktsignaler og fra oscillatoren (VCO) avgitte oscillatortaktsignaler, en fasekontrollinnretning (PR) som etter storrelsen av på utgangen av fasekom-paratoren opptredende sammenligningssig-naler genererer digitale kontrollsignaler og en ved de digitale kontrollsignaler pådratt digital/analog-omformer (D/A) som avgir til disse digitale kontrollsignaler motsvarende analoge styrespenninger til oscillatoren. I den forbindelse er det i fasekontrollinnretningen (PR) anordnet en lageranordning (SP) i hvilken en rekke av de ved fasekontrollinnretningen genererte, påfølgende digitale kontrollsignaler lagres. Disse stilles til rådighet ved utfall av referansetaktsignalene (RF).
