FIELD: operational, indirect, structural analysis of dispersive systems. SUBSTANCE: method of processing of signals of acoustic emission of generated dispersive systems consists in identification of elements of examined dispersive system by discrete Fourier spectrum. Signals are processed by isolation of modal harmonics from common discrete Fourier spectrum. Frequencies of significant fundamental harmonics and timbre harmonics accompanying them are found on basis of analysis of frequencies and they are used to form subspectra from common discrete Fourier spectrum. Each subspectrum corresponds to certain element of examined dispersive system and comprises fundamental and timbre harmonics corresponding to it. Quantitative composition of each isolated element is established by relation of capacity of subspectrum obtained for given element to capacity of common discrete Fourier spectrum with use of data generated for reference mixture with known percentage of given element. EFFECT: increased accuracy and reliability of processing of acoustic signals of generated systems with simplification of procedure of determination of element composition of analyzed system. 2 dwg, 1 tbl
