摘要：
The most direct manifestation of complexity of CDW dynamics and a possible clue to its understanding is a signal produced when CDW is brought to motion in electric fields. The signal produced by moving CDW in mesoscopic samples of ortho-TaS3 studied by means of wavelet based methods with a special emphasis to a broad-band noise and its relation to narrow-band signal. It has been shown that the singularity points in the noise signal can be identified using wavelet transform modulus maxima method. These points are believed to correspond to moments when a strong scattering of CDW occurs.
