Comparison of Orthogonal Transforms for Teleseismic Data
Abstract
The availability of fast algorithms for computing the orthogonal transforms such as the fast Fourier transform (FFT), Walsh-Hadamard transform (WHT), discrete Chebyshev transform (DCT), and related transforms has made such transforms increasingly popular in data processing. This paper is concerned with the comparative evaluation of these transforms as applied to the ACDA teleseismic data. Computer results and program listings are provided. The paper is concluded with the recommendation that better orthogonal transforms are needed for both signal processing and seismic discrimination.
