Abstract
A new method based on the double wavelet transform is proposed for the analysis of features related to the interaction of modes in nonstationary dynamics of systems with several time scales. Examples are presented, which illustrate new possibilities offered by the proposed method in determining the characteristics of amplitude and frequency modulation from the time series of complex oscillatory processes.
