Claims (3)

1. Förfarande för att leda styrspänningen frän en logikdel tili radiofrekvensdelens styrbara elkopplare i en radiotele-fon, dä hos radiofrekvensdelen bildas erforderliga frekven- 5 ser medelst frekvenssyntetisatorkretsar (1) omfattande en fasläsningskrets eller tili en fasläsningskrets hörande funktionella block, vilkas frekvenser ändras sälunda att sagda logikdel sänder för frekvensändringen erforderliga styrningsburster via styrlinjer (a, b, c) tili syntetisa-10 torerna, kannetecknat av att - en kopplingslinje (d, e) tili de styrbara elkopplarna utanför syntetisatorkretsarna har avgrenats frän en eller flera styrlinjer tili syntetisatorn, - under den tid dä syntetisatorkretsen (l) mottar ingen 15 styrning, utger logikdelen styrspänningen för de styrbara elkopplarna via styrlinjen (a, b) tili syntetisatorn och via den frän denna avgrenade kopplingslinjen (d, e).
2. Förfarande enligt patentkravet 1, kännetecknat av att 20 tillträdet av styrningspulserna för syntetisatorn tili kopp- lingslinjerna (d, e) hindras genom att koppia ett lägpass-filter (2, 3) tili dessa linjer.
3. Förfarande enligt patentkravet 1, kännetecknat av att '25 kopplingslinjen inte avgrenas frän den styrlinje (c) genom vilken logikdelen sänder en enable-puls.
