Book Review:
This book is a substantially expanded edition of An Introduction to Random Vibrations and Spectral Analysis which now covers wavelet analysis.
The wavelet transform is a new method of signal decomposition. It is a major development in vibration analysis that has taken place since the last edition was completed. A signal’s mean-square is broken down into its contributions from different frequencies and different times and the result displayed as a countour map. This display has been likened to the way that notes are shown on a musical scale. It allows the changing spectral composition of non-stationary signals to be measured and compared.
All the material on random vibrations and spectral analysis, that proved so popular in the first two editions, has been retained; but now it is supplemented by an extensive new chapter on wavelet analysis. Basic theory is thoroughly described and illustrated, with a detailed explanation of how discrete wavelet transforms work. Computer algorithms are expalined and supported by examples and set of problems. An appendix lists 10 computer programs for calculating and displaying wavelet transforms.
Key features:
• Retains complete introduction to random vibration and spectral analysis theory
• One of the first books to explain wavelet analysis to engineers
• Presents original material on discrete wavelet analysis in an extensive new Chapter 17
• Provides a new appendix of wavelet computer programs in the high level language MATLAB (R)
• 27 new diagrams and graphs support and clarify the next
• Simplifies complicated mathematics wherever possible
This book is intended to be used as a self-contained text by senior undergarduates in engineering and the applied sciences, and by postgraduates concerned with vibration and signal analysis. It will also be an important source for engineers in industry who will welcome it as a new reference to practical wavelet analysis.
