ABSTRACT
Abstract The functions in the Digital Subscriber Line (DSL) analog frontend (AFE) can be grouped into three general areas: transmitter, receiver, and hybrid. The transmitter transforms the digital representation of the transmit signal into a form that can be launched into the twisted-pair cable. The receiver senses the signal being transmitted from the far end of the loop and digitizes it such that it can be processed, i.e., demodulated, by the digital section. The hybrid couples the receiver and transmitter to the line to minimize the amount of transmit signal superimposed on the receive signal.
