Abstract

On a basis of theory of automated following the frequency of input signal systems in dynamic mode we have obtained analytical expression for transient frequency of general frequency filters tuning. As a result we have proved a possibility of MathCAD application for filter self-tuning process. Taking into account known features of non-stationery process active spectrum, we have obtained another possibility of mentioned calculations. We propose an algorithm for these calculations for general filters. We note that known problem of mathematical analysis of general following filters is solved.
