Powerline communication (PLC) modem employing an analog electromagnetic transducer

摘要

A PLC cable modem is provided which includes an analog electromagnetic field transducer for generating an electromagnetic field based on an analog electrical signal and also for generating an analog electrical signal based on an electromagnetic field. The PLC cable modem also includes an analog signal processing unit operatively coupled to the analog electromagnetic field transducer and a digital signal processing unit for processing signals received from (or to be sent to) the analog signal processing unit. An interface port is provided for communicating digital signals to and from a data transmission or receiving device.
