Patent ID: 7388904

Claim:
A transceiver, comprising: a receiver portion including at least one receiver to receive signals from a complementary transmitter through a single differential electrically conducting pair, the at least one receiver including a plurality of demodulators to receive the signals from a corresponding plurality of frequency separated channels, wherein the plurality of demodulators includes at least one down-converting demodulator, the down-converting demodulator comprising: an analog down converter coupled to receive an analog signal from the transmission medium and generate base-band signals corresponding to signals transmitted at a specific carrier frequency on the transmission medium; an analog-to-digital converter coupled to the down converter to provide a digitized base-band signal; and a decoder coupled to the analog-to-digital converter to provide data signals in response to the base-band signals; and an interference filter coupled to the receiver portion to substantially reduce interference in signals received by the receiver portion that result from transmission coupled to each of the plurality of corresponding frequency separated channels from transmitters other than the complementary transmitter.
