A new method based on the wavelet analysis of the voltage oscillations generated above threshold electric field for depinning of the charge density wave (CDW) in the molecular conductor (Perylene) 2Pt(mnt) 2 (mnt=maleonitriledithiolate) has been developed. This analysis method permits a better time resolution of the frequencies and phases involved in the CDW motion than that allowed by conventional Fourier analysis. The results are discussed in relation with current models for CDW deformations.
