Spectral Analysis and the FFT,tribution in some manner, and the one chosen here is by way of the discrete Fourier transform (DFT.) This has two advantages. First, many of the ideas and methods of time series analysis can be borrowed and used for the present purposes. Second, it allows the use of the very efficient fast Fourier transform (FFT) computer algorithm.

Spectral Analysis of Wave Motion,f Reference . The application of Fourier series, however, is quite limited with the exceptions being References . It appears that the task of performing the summation is too formidable since a large number of terms are required to adequately describe the wave. With the advent of
