Abstract

The invention relates to a method for optimizing a transmission segment having a minimal-phase transmission characteristic (9; 9') from a transmission segment having a non-minimal-phase transmission characteristic (8) upstream of an equalizer (7), generating the transmission segment having a minimal-phase transmission characteristic (9; 9') from the transmission segment having a non-minimal-phase transmission characteristic (8) and a prefilter (6;6<SUP>(1)</SUP>, 6<SUP>(2)</SUP>,..., 6<SUP>(n)</SUP> ). In order to determine the transmission characteristic (H
