Spectral Analysis of Wave Motion,ntial equations. In doing so, certain key ideas emerge which recur throughout this book; central among these ideas are that of a wave mode, its spectrum relation, and its phase and group speeds. The application of Fourier analysis to periodically extended structures is also discussed.

Spectral Analysis of Wave Motion,urces of errors in using it on finite samples and ways of reducing their influences are discussed. The Fourier transform is then applied to wave analysis. The crucial step is to set up the connection between the spectral responses at different space locations—we do this through the governing differe
