TRACKING AND RESAMPLING METHOD FOR MONITORING THE PERFORMANCE OF ROTATING MACHINES Abstract of the Detailed Description A tracking and resampling method for monitoring the performance of a rotating machine (10) is disclosed. One or more measuring devices (13) provide rotating machine performance data to a signal processor (14) that samples the performance data at uniform time increments. A digitized waveform of the sampled performance data is interpolated by an interpolation filter. The sampledperformance data is convolved with the impulse response of the interpolation filter to provide a continuous time function waveform depicting the rotating machine performance data. The signal processor (14) resamples the continuous time function waveform at uniform rotating shaft phase angle increments.
