Abstract
Power spectral densities are taken at periodic intervals for preselected indicator parameters and these power spectral density profiles are compared to a reference magnitude of a power spectral density profile for purposes of prognosticated future failures. The power spectral density profile can be for any one of a plurality of indicator profiles, such as an accelerometer output, the output of a pressure sensor, or a voltage output from an ignition system.
