Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Improvement of the methods for the transformation of signal orthogonal components into amplitude Chekushkin V.V., Averyanov A.M. Comparative analysis and optimization of high-speed multinomial algorithms for calculation of functions like , using criterias of transformation time, accuracy, soft- and hardware needs are executed here. Precision from 3 to 20 bits of fractional part is provided for control and diagnostic systems. Key words: orthogonal components of signal, polynomial algorithms of fast – acting, optimization of Chebyshev’s polynomials. Контактная информация: e-mail: ave-skz@mail.ru.
