Abstract

Oppfinnelsen angår en fremgangsmåte for å styre en frekvens-syntetisator og en frekvens-syntetisator som har en styrbar utgangssignal frekvens og som omfatter en direkte digital syntetisator (100) hvis utgangssignal kobles til inn- gangen til en faselåst sløyfe (102). For å redusere innstillingstiden til syntetisator- en omfatter den direkte digitale syntetisatoren (100) anordning (204) for å styre frekvensen til den direkte digitale syntetisatoren fra en første frekvens til en andre frekvens i overensstemmelse med forhåndsbestemte frekvenstrinn.
