A method and apparatus for adapting an equalizer coefficients to a channel comprising filtering a high frequency error monitor slicer output and a data slicer output to isolate selected high frequency symbol values. Filtering a low frequency error monitor slicer output and the data slicer output to isolate selected low frequency symbol values. Generating a high frequency error monitor slicer threshold signal with a first adaptation module. Generating a low frequency error monitor slicer threshold signal with the first adaptation module or a second adaption module. Combining the high frequency error monitor slicer threshold signal and the low frequency error monitor slicer threshold signal to generate a difference signal. Integrating the difference signal with an accumulator to generate equalizer coefficients to adapt the equalizer to the channel. Providing the high frequency and low frequency error monitor slicer threshold signal to respective slicers.
