METHOD OF SPECTRAL ANALYSIS OF QUASI-PERIODIC SIGNALS

摘要

FIELD: identification of radio engineering and biomedical signals. SUBSTANCE: in agreement with invention two-dimensional spectrum presented in the form of half-tone image is obtained as result of individual realizations of quasi-periodic process. This image is them compared with image obtained by similar spectral conversion of standard signal. Novelty of method consists in that to obtain two-dimensional spectrum of signal first equalization of duration of each realization is carried out by means of unidimensional forward and backward spectral conversions and two-dimensional spectra of initial and standard signals are masked in advance. EFFECT: increased authenticity of method.
