Аннотация:Method of continuous wavelet transform Morley (chosen by us from a comparison of the most used 5 mother wavelet) was applied to time-frequency analysis of indices of solar activ-ity: W, F10,7, Mg II 280 nm, F530, Flare Index and Counts of flares. Simultaneously with the maximum amplitude of the main 11-year cycle of solar activity we identified several low-amplitude cycles with periods (1,3 - 100 years). The frequency-time characteristics of wavelet representations are very similar to each other. We also found some differences in the results caused by stochastic processes in time of maxima and minima of the 11-year cycle.
