1. A method for reducing effects of Electromagnetic Interference (EMI) in an Ethernet system, comprising:

  • computing and storing filter coefficients corresponding to a range of EMI frequencies;

    receiving a signal;

    detecting the EMI in the received signal;

    determining a frequency of the EMI;

    selecting a subset of the stored filter coefficients for a Feed Forward Equalizer (FFE) and a Decision Feedback Equalizer (DFE) corresponding to the determined frequency of the EMI; and

    adjusting a frequency response of the FFE and the DFE using the selected subset of the stored filter coefficients so as to reduce effects of the EMI in the received signal.
