Abstract

Det er beskrevet en flerkanalssender som har en forforsterker (8a, 8b, 8c) med variabel forsterkning for hver kanal, idet de sammensatte utgangssignaler mates til en linearisert effektforsterker (10) med flere kanaler. Utgangssignalet fra sistnevnte samples ved hjelp av koblingsutstyr (12) som frembringer et samplet signal representativt for effektnivået i hver kanal. Det samplede signal tilføres en frekvensselektiv tilbakekoblingssløyfe som for hver kanal frembringer et styresignal (20a, 20b, 20c) som tilføres den tilhørende forforsterker (8a, 8b, 8c) for å variere sistnevntes forsterkning i den hensikt å frembringe adskilt effektstyring for hver kanal.
