Claim Text:
1. A system comprising: a plurality of sensors, each monitoring at least one parameter associated with the system; a controller configured to receive a signal representing the monitored at least one parameter from each of the plurality of sensors and adjust a function of the system based on the received signals; and respective discrete wavelet transform components associated with each of the plurality of sensors, each of the discrete wavelet transform components configured to provide a set of discrete wavelet transform coefficients representing a content of the signal for its associated sensor to a discrete wavelet transform monitoring component; a signal reconstruction component configured to reconstruct a portion of the signal only from a set of discrete wavelet transform coefficients that fall outside of associated defined range of values; and a fault analysis component configured to evaluate the reconstructed portion of the signal to identify an anomaly that is represented by the set of discrete wavelet transform coefficient falling outside of the defined range of values.
