摘要

The multiscale dynamics of glow discharge plasma is analysed through wavelettransform, whose scale dependent variable window size aptly captures bothtransients and non-stationary periodic behavior. The optimal time-frequencylocalization ability of the continuous Morlet wavelet is found to identify thescale dependent periodic modulations efficiently, as also the emergence ofneutral turbulence and dissipation, whereas the discrete Daubechies basis sethas been used for detrending the temporal behavior to reveal themulti-fractality of the underlying dynamics. The scaling ex- ponents and theHurst exponent have been estimated through wavelet based detrended fluctuationanalysis,and also Fourier methods and rescale range analysis.
