  The multiscale dynamics of glow discharge plasma is analysed through wavelet
transform, whose scale dependent variable window size aptly captures both
transients and non-stationary periodic behavior. The optimal time-frequency
localization ability of the continuous Morlet wavelet is found to identify the
scale dependent periodic modulations efficiently, as also the emergence of
neutral turbulence and dissipation, whereas the discrete Daubechies basis set
has been used for detrending the temporal behavior to reveal the
multi-fractality of the underlying dynamics. The scaling ex- ponents and the
Hurst exponent have been estimated through wavelet based detrended fluctuation
analysis,and also Fourier methods and rescale range analysis.
