Abstract
Fremgangsmåte for regulering av forsterkningen av en mottakerkrets i den hensikt å bedre denne krets' og den tilhørende mottakers immunitet overfor inter- ferens . Kretsen har en inngangsf orsterker (115) av lavstøytypen for å forsterke mottatte signaler, og effektnivået etter forsterkningen reguleres ved å endre inn- gangsforsterkerens forsterkning eller å frakople/tilkople den. Resultatet av effektnivåmålingen sammenliknes periodisk med en terskelverdi, og når måleresultatet overstiger denne frakoples inngangsfor- sterkeren. Den koples imidlertid inn igjen når målingen tilsier at effektnivået er lavere enn terskelverdien, og når det samtidig ikke registreres noen vesentlige intermodulasjonsprodukter som følge av interferenspåtrykk. Registreringen av slike produkter kan skje ved kortvarig å kople inn inngangs- forsterkeren (115) og registrere den til- hørende endring i målt effektnivå. Over- skrider endringen en gitt verdi foreligger betydelige intermodulasjonsprodukter, og inngangsforsterkeren koples da ikke inn, ellers har man en situasjon hvor det ikke foreligger noe betydelig interferenspå- trykk, og forsterkeren koples da inn igjen.
