Description: Wavelet transform is applied to the analysis of vibration signatures in order to verify the ability      of the detection of abnormal condition. It can well describe the dynamics of the signal's      spectral composition of a non- stationary and stationary signal to be measured and presented      in the form of 3-D time-frequency map. Although wavelet has been developed over about ten      years in the mathematics and physics, its engineering applications is a first stage. The objective      of this report outlines the definition of the wavelet transform and is to discuss the properties of      the wavelet transform as new tool for the vibration analysis, and then demonstrates how it may      be applied to the machinery condition monitoring.
