1. A method for equalizing a digital signal at an equalizer, comprising:
receiving, at the equalizer, a plurality of samples of the signal in a plurality of unit intervals (UIs) of a channel response of the digital signal, the plurality of samples comprising a first plurality of samples of a primary response and a second plurality of samples of one or more reflection responses;
equalizing, by the equalizer, the first plurality of samples using a first set bitwidth;
equalizing the second plurality of samples using one or more further set bitwidths, wherein the first set bitwidth is greater than each of the one or more further set bitwidths; and
generating, by the equalizer, an equalized digital signal.
