Drift
Drift is a term in telecommunication system that is a comparatively long-term change in an attribute or value of a system or equipment operational parameter. Drift is usually undesirable and unidirectional, but may be bidirectional, cyclic, or of such a long-term duration and low excursion rate as to be negligible. The drift can be characterized as "diurnal frequency drift" and "output level drift".
