FIELD: physics.SUBSTANCE: invention relates to means of analysing a signal image. The method includes selecting two subsystems in which processes are observed in form of synchronised quasi-periodic signals x(t) and x(t), synchronously recording signals during a time T, constructing a phase portrait of the analysed dynamic system on the interval T in coordinates x(t)-x(t), determining a closed curve delineating the portrait, determining Fourier descriptors of the closed curve, classifying the system using a trained classifier constructed in the space of Fourier descriptors.EFFECT: high information value of signal analysis data.3 cl, 13 dwg |
