N.2016-09-202016-09-202015http://openarchive.nure.ua/handle/document/2907The theoretical basis and practical peculiarities of the system spectral analysis are briefly considered. The necessity and the expediency of simultaneously application of different linear and non-linear integral transforms during the system spectral analysis performance are explained. The system spectral analysis usage for investigations of the time-frequency structure of the fractal ultra-wideband signals is shown to be effective and useful.ensystem spectral analysisultra-wideband signalsArticle
