      abstract = {A system, method and program product for predictive  condition monitoring of a monitored system by means of  sub-band decomposition of a complex monitored signal.  Features of the decomposed signal are extracted for  modeling estimation and detection of deviations in the  features. Deviations are indicative of impending monitored  system fault.},
