Wavelet Analysis of Vibration: Part 2—Wavelet Maps
David E. Newland · Journal of vibration and acoustics · 1994
Wavelet maps provide a graphical picture of the frequency composition of a vibration signal. This paper, which is Part 2 of a pair, describes their construction and properties. In the case of harmonic wavelets, there are close similarities between wavelet maps and sonograms. A range of practical examples illustrate how the wavelet method may be applied to vibration analysis and some of its advantages.
