  • System, apparatus, and method for at least mitigating a signal reflection
    Patent number: 10135548
    Abstract: An apparatus, system, and method are provided for at least mitigating a signal reflection. Included is a filter configured to receive a data signal for transmission, and filter the data signal to generate a filtered data signal. Also included is a gain regulator in electrical communication with the filter. The gain regulator is configured to receive the filtered data signal for adjusting a gain of the filtered data signal to generate a gain regulator output signal for use in at least mitigating a signal reflection. Further, a controller is provided in electrical communication with the filter and the gain regulator. The controller is configured to receive the filtered data signal, and process the filtered data signal to generate at least one controller output signal for use in controlling the filter and the gain regulator.
