| Some machines, such as gear boxes, produce very complicated spectrum signatures. The cepstrum analysis offers a way to simplify the analysis, of these signals. When trying to diagnose a vibration signal in order to identify possible faults in the machine, the following are investigated: - harmonic relations,
- presence of sidebands,
- the relation of energy in different side band and harmonic families.
The cepstrum analysis - simplifies the analysis of a complicated spectrum, and
- is independent of the signal path.
