Abstract

En flerbærebølge-radiosender har kombineringsanordninger for å motta og kombinere flere bærebølger som innbefatter en første, modulert bærebølge for sending i en første kanal, og en andre, modulert bærebølge for sending i en andre kanal, for å skape et flerbærebølge-signal. Det er tilveiebrakt effektstyringsanord- ninger for å variere individuelt effekten for hver av de flere bærebølgene før kombinering.
