Explanation of recent Shapiro steps studies in CDW conductors requires consideration of internal degrees of freedom and of associated finite velocity correlation lengths. The synchronization of different regions of the specimens with increasing rf is demonstrated through coalescence of noise peaks, reduction of fluctuations in noise peaks, and narrowing of steps.
