Abstract : File characteristics: Software (6 files). Physical description 1 computer diskette, 3 1/2 in, high density, 1.4MB. System requirements: IBM-PC compatible, MS-DOS, FORTRAN. As with Fourier analysis, the basic idea behind wavelet analysis is to decompose a function into the sum of meaningful basis functions. Unlike Fourier methods, however, the basis functions of wavelet analysis exhibit some form of localisation in both the frequency and time domains. Discrete wavelet analysis is described through the dilation equation approach. A practical implementation of these techniques is developed and the resulting software can perform fairly comprehensive analyses. Several examples of its use are included and amply demonstrate the potential.
