L Gelman, B Murray, T H Patel, and A Thomson inform about a novel wavelet technology for vibration condition monitoring of rolling element bearings. The use of wavelets offers two clear advantages where the demodulation frequency band based on wavelets can separate closely-spaced, narrowband resonances and wavelets could cover all the fault-excited frequency regions available in the signal by using proper wavelet parameters. The estimation of the wavelet diagnostic feature requires a choice and adjustment of several parameters: a choice of centre frequency and bandwidth parameter of the mother wavelet, and the frequency band of integration.
