The Transients in Frequency Selective Systems at an Impact of Modulated Radio Pulse

摘要

The features of abbreviated operator equation method application to the selective dynamic systems with the natural frequencies of any order are considered. The method consists in representation of the operator circuit function in the form of a sum of elementary fractions divided into two operators. Fractions located in the upper part of the s-plane are concerned to the first operator, while fractions located in the lower part of the s-plane are concerned to the second operator. At resonant influence, the first operator defines the main component of solution, while the second operator defines the amendment of the damping order or less. For the first time, the calculation expressions (exact and abbreviated) are obtained in the closed form, on the base of a set of simple recurrent expressions for transient characteristics of the complicated selective systems at the impact of radio pulses with the arbitrary intra-pulses modulation.
