| Abstract: | Earlier it has been found that the signal produced by a moving CDW contains along with fundamental of narrow band frequency (ω1) and its harmonics (ωn) a non-coherent part—a lot of non-coherent oscillations. Due to a rather broad frequency range the power associated with non-coherent oscillations is comparable to or even greater than that for fundamental frequency, and hence, can play an essential role in CDW dynamics. |
