Abstract
This invention is to propose both a signal processing method and its computational algorithm to apply in the diagnosis of component defects for mechanical systems. A demodulation function for signal processing is used to excellently demodulate the vibration signal and can be applied to present a 3-D spectrum. To implement the function, both the signal processing method and its computational algorithm is proposed and would provide a convenient tool in constructing the 3-D spectrum. From the sense of sight, the 3-D spectral pattern would be very useful in the defect diagnosis.
