Abstract
Tidskonstanten som bestemmes av en høyhastlghets tidskonstantkrets (32) er egnet for høyhastighetsveks- ling av en utgangsfrekvens (fø), og den tldskonstant som bestemmes av lavhastlghets tldskonstantkretsen (33, 34) er egnet til stabilisering av utgangsfrekvens (fø) på en tilsvarende verdi og undertrykkelse av en falsk utgangsfrekvens. Når utgangsfrekvensen (f0) veksles fra (fa) til for eksempel (f^), veksles utgangsfrekvensen (f0) ved innstilling av dellngsforholdet (n) for frekvensen når bryteren (Sa) er PÅ, mens bryteren (S^,) er AV. Samtidig slås bryteren (Sa) av, og etter at utgangsfrekvensen (fø) er stabilisert, slås bryteren (SD) på. Hastigheten for veksllngen av utgangfrekvensen (fø) økes og en falsk utgangsfrekvens etter frekvens- vekslIngen undertrykkes uten bruk av noen A/D-omformer eller en D/A-omformer som har høy nøyaktighet.
