Aerospace Instrument-Making Annotation << Back CALCULATION OF SPECTRAL TRIAD OF REAL VARIABLE FUNCTION I.Ya. Ogurtsov A new transformation of real variable function – the spectral triad, is calculated without numerical solutions of differential equations. Rough calculations are solely applicable to sine- cosine transformations according to Fourier-transform spectroscopy, which unite spectral triad with integral transformation. There begins the formation of main calculation phases, design equations are produced assuming that module of logarithmic decrement is constant. To calculate the module a formula is deduced. The results of the research are sufficient for creating a mashine code for computer calculations with implementation of already known constituent programs. Key words: the spectral triad, Fourier integral transformation, module of logarithmic decrement. E-mail: office@nwpi.ru
