ABSTRACT:
In general, in one aspect, the disclosure describes a digital signal equalizer that includes a plurality of multiplexers. The number of multiplexers defines resolution of equalization. The plurality of multiplexers are configured in groups. The number of groups is based on number of taps, and the number of multiplexers associated with a particular group is based on equalization range for the group. The multiplexers in each group select a digital value associated with the cursor or a non-cursor tap associated with the group.
