    Abstract

    This paper describes a method for design of linear- and minimum-phase equalizers using only magnitude specifications. The method consists of 2 steps. First a linear-phase equalizer is designed and secondly it is transformed to minimum-phase.The linear-phase equalizer is the result of minimizing an error function which is quadratic in the filtercoefficients. The advantage of the quadratic function is the ability to find the optimal coefficients solving a system of linear equations without iterations.The transformation to a minimum-phase equalizer is carried out by homomorphic deconvolution. In this way we avoid the normal root-finding procedure which is time consuming and can be inaccurate when polynomials of higher order are considered.
