Abstract

Et signaloverføringssystem omfatter utsluXnlngSXretser utstyrt med en brokobllng hvor utbalansert tilstand kan oppnås Innenfor hele det frekvensbånd som kan tintyttes for signaloverføring over en trådllnje. eller en vesentlig del av dette bånd. En s&dan utslukningskrets tillater samtidig toveis IcommvuilkasJon Idet samme eller Innbyrdes nærliggende frekvenser utnyttes for overføringen. En sådan utslukningskrets er da anordnet i hver ende av vedkommende slgnaloverferlngsllnje, således at denne kan utnyttes for samtidig signaloverføring 1 begge retninger.
