Detailed measurements of current-oscillation phenomena in NbSe3 and TaS3 show that the harmonic content and amplitude of the oscillations remains large even at very high electric fields. These results are well described by overdamped motion in a nonsinusoidal pinning potential of the general type previously proposed by Bardeen. Transient "ringing" in the voltage response to a current pulse is attributed to charge-density-wave dephasing. This dephasing is associated with crystal defects, such as dislocations, and with contact effects.
