This paper provides an effective method for design of the analog allpass filter for equalization of the group delay frequency response. This method is based on combination of the differential evolution algorithm and modified Remez second algorithm. We are able to propose equalizers with equiripple group delay response in the passband of the lowpass filters. The procedure works automatically without an input estimation. The method is illustrated on numerical examples
