Abstract:
A signal separation device, comprising:a terminal for coupling to a conductor transporting simultaneously a first and a second signal having different frequency ranges, the second signal being characterized by a transmit component and by a receive component;a first filter coupled to said terminal for extracting the first signal;a second filter coupled to said terminal for rejecting the first signal, said second filter including a transformer having a first winding and a second winding magnetically coupled to one another, said first winding being electrically coupled to said terminal;a junction circuit, including:a) a transmit component output electrically coupled to said second winding for impressing at said first winding the transmit component of the second signal;b) a composite signal input separate from said transmit component output, said composite signal input electrically coupled to said second winding for receiving a composite signal being a combination of the transmit component and the receive component of the second signal;c) a processing unit for receiving the transmit component of the second signal and the composite signal and generating the receive component of the second signal;d) a receive component output coupled to said processing unit for issuing the receive component of the second signal.
