A Review on Applications of the Wavelet Transform Technique in Spectral Analysis

[摘要] Starting from 1989, a new technique known as wavelet transforms (WT) has been applied successfully for analysis of different types of spectra. WT offers certain advantages over Fourier transforms for analysis of signals. A review of using this technique through spectral analysis is presented. The mathematical principles of applying WT in processing gamma spectra have been discussed.
