Abstract
In an equalizer filter unit, the filter is divided into a plurality of sequential segments. While all the components of the equalizer unit multiply data signal groups by the a coefficient signal group, in only one segment are the coefficient signal groups updated. The data and the coefficient signal groups are periodically transferred to the next sequential filter segment while the filter segments are reconfigured in the original sequential order. In this manner, the each data signal group interacts with a coefficient signal group in the original sequential order. Because the coefficients are updated in only one of the filter segments, the amount of apparatus required for processing signal groups is reduced.
