Wavelet Theory Based Multiple Scale Analysis for Vibration Signals
Fei Ma · Noise and Vibration Control · 2004
In this paper, the basic wavelet theory is introduced, in the scope of continuous wavelet transform, Mallat arithmetic and scale function. Application of the theory to process the vibration signals is illustrated in the use of signal with non-balanced property to be de-noised and to be analyzed. At the last, from the comparison of two results, the conclusion is drawn that the scale would affect the result.
