Abstract This paper proposes a method based on evolutionary strategies (ES) for design ofmultiplier-less two-channel perfect-reconstruction (PR) filter banks (FB). The filter banks are jbased on the modified lifting scheme structure. A new ES given a seed is proposed to find the *sum of power-of-two (SOPOT) coefficient of the filter bank. This method requires much less 玠esign time than genetic algorithm. Finally, a PR FB with SOPOT coefficient is given as an :example to illustrate the proposed method.
