摘要：

In this paper optimal phase equalization with all-pass filters using the Chebyshev error criterion is considered. The most important results of non-linear approximation theory as well as a Remez-type algorithm for the construction of the best solution are presented. Some examples illustrate the efficiency of the new method. Linear and quadratic phase functions can be approximated, too.
