Abstract

Filters with the minimally possible quality of the poles are considered in this paper. The possibility for the increase of the selectivity of these filters through forming a numerator of a transfer function of a special type is shown. An algorithm used when calculating transfer functions by means of optimization functions of the MATLAB package is demonstrated. Plots of gain-frequency characteristics of the synthesized filters are shown.
