Выведенные выражения позволяют выбрать оптимальный метод и необходимое число отсчетов сложного входного сигнала. Определены границы погрешности предложенного метода обработки сигнала с учетом влияния отсечения. Проведено математическое моделирование предложенных процедур оценки возможной погрешности отсечения.</p></abstract><trans-abstract xml:lang="en"><p>The paper deals with the problem of estimating the value of truncation error in case of asynchronous sampling of the AC signal in presence of sub- and interharmonics. On the base of derived relation it is possible to select the best processing method and select the necessary number of samples in case of  complex input signal. The paper investigates the errors related to the proposed processing method, and provides the uncertainty bound. The simulation of suggested procedure is also carried out.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>асинхронная дискретизация</kwd><kwd>интер- и субгармоники</kwd><kwd>активная мощность</kwd><kwd>математическое моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>asynchronous sampling</kwd><kwd>inter- and subharmonics</kwd><kwd>active power</kwd><kwd>mathematical simulation</kwd><kwd>experimental results</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">Testa A., Langella R.
