Abstract
A method and device for processing quasi-periodic signals from machines that provides improved diagnostic results. A dynamic, non-uniform signal termed the speed clock controls processing of the signals. This processing prevents the leakage artifacts and poor frequency resolution that can mask signal components and limit the diagnostic value of existing technology. Valuable phase information, which is destroyed by existing sampling methods controlled directly by encoder signals, is retained. The invention also enables removal of large masking signal components without otherwise altering the signal. By preventing artifacts, retaining phase information, and removing undesirable signal components, the present invention is a dramatic improvement over existing technology for processing signals to determine the health and performance of operating machines.
