Abstract
A system and method for processing a communication signal from a wireline is provided. The system comprises a coupling unit and signal processing circuitry. The coupling unit comprises a transformer and is configured to receive the communication signal from the wireline. The coupling unit is also configured to generate a first signal based on amplifying or attenuating the communication signal according to a first winding ratio of the transformer and a second signal based on amplifying or attenuating the communication signal according to a second winding ratio of the transformer. The signal processing circuitry is configured to process the first signal and the second signal.

A system for processing a communication signal from a wireline, the system comprising:
- a coupling unit comprising a transformer and configured to receive the communication signal from the wireline, the transformer including a primary coil and a secondary coil, the secondary coil including a plurality of taps, the coupling unit:
- generating a first signal based on amplifying the communication signal from a first winding ratio of the transformer determined by selecting a first set of the plurality of taps, and
- generating a second signal according to a second winding ratio of the transformer determined by selecting a second set of the plurality of taps;
- and
- signal processing circuitry configured to process the first signal and the second signal.
A method for processing a communication signal from a wireline, the method comprising:
- receiving the communication signal from a wireline at a coupling unit comprising a transformer including a primary coil and a secondary coil, the secondary coil including a plurality of taps;
- in the coupling unit, generating a first signal based on amplifying or attenuating the communication signal using a first winding ratio of the transformer determined by selecting a first set of the plurality of taps;
- in the coupling unit, generating a second signal based on amplifying or attenuating the communication signal using a second winding ratio of the transformer determined by selecting a second set of the plurality of taps;
- and
- processing the first signal and the second signal in signal processing circuitry.
