Abstract: A circuit for interfacing an AF line to a central unit makes use of an RF transformer Tr. Said transformer is so arranged that the source AF signal to be transmitted modulates an RF carrier generated in a primary winding of the transformer and the resulting modulated signal in the secondary winding is demodulated before being transmitted to a line which is thereby linked to the source.
