ABSTRACT:
An FDTS/DF equalizer using absolute value calculation includes: a feed-forward filter receiving and filtering a sampled signal; a feed-back filter filtering a restored data; a subtractor obtaining a difference between signals respectively filtered by the feed-forward filter and the feed-back filter; and a detector receiving the subtracted signal and detecting a data using absolute value calculation. The FDTS/DF equalizer in the reproducing terminal which reproduces a data passing through a channel performs an absolute value operation by using the adder, so that the number of gates can be reduced, the calculation speed can be improved, and the size of a chip can be reduced.
