Analytical Synthesis of Parameter-Varying Filter of Constant Component with Application to Switching Systems

In this paper, we propose a concept of a continuous-time filter of constant component that exhibits a very short response in the time domain if compared to the traditio nal time-invariant filter. The improvement of the filter dynamics was achieved as a result of the time-varying p arameters which were introduced to the filter structure. Such a designed filter is then applied in a system whic h switches many distorted signals which should be filtered as fast as possible. The paper is of review nature and presents both a theoretical background of the proposed filter and the results of simulations.
