Разработан алгоритм расчета временных характеристик, обеспечивающий построение эффективной автоматизированной процедуры моделирования сигналов, звеньев и реакций во временной области. Проведен сравнительный количественный анализ точности предлагаемого алгоритма и алгоритма дискретного преобразования Фурье.</p></abstract><trans-abstract xml:lang="en"><p>A single mathematical model of time characteristics of signals, links and responses of telecommunications and radioelectronics systems is suggested. It embodies Dirac- and Heaviside responses of all types of linear links, as well as their responses to the input in the form of periodic signals, no periodic finite and no periodic eternal signals. On the basis of the suggested model the algorithm for calculation of time characteristics was developed, which allows creation of effective automated simulations procedure of signals, links and responses in time-domain. The comparative quantitative analysis of accuracy of the suggested algorithm and discrete Fourier transformation (DFT) algorithm was carried out.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>система</kwd><kwd>звено</kwd><kwd>сигнал</kwd><kwd>реакция</kwd><kwd>характеристика</kwd><kwd>линейность</kwd><kwd>модель</kwd><kwd>алгоритм</kwd><kwd>точность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>system</kwd><kwd>link</kwd><kwd>signal</kwd><kwd>response</kwd><kwd>characteristic</kwd><kwd>linearity</kwd><kwd>model</kwd><kwd>algorithm</kwd><kwd>accuracy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Беленкевич Н.И., Ильинков В.А.
