Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Structural designing the digital spectral analyzers for on-line calculation of Fourier factors estimations based on sign-function stochastic quantization Yakimov V.N. The article deals with the problem of efficiency increasing in the digital computing for harmonic analysis of multicomponent oscillating processes. For these purposes the sign-function stochastic quantization is used. Fast digital algorithms identifying the harmonic spectral components in broadband stationary noise are cited. On the basis of the given algorithms block diagrams of multichannel digital spectral analyzers are developed for on-line calculation to estimate the Fourier factors.
