| Abstract: | The paper analyses the deficiencies of time-frequency resolution in short window time Fourier transform,and sketches out both wavelet transform concept and multiresolution analysis. Multiresolution property of wavelet transform is then used to make the time-frequency analysis and processing of seismic and log signals. Experiments show that the multiresolution analysis of wavelet transform is an effective new method for processing unstable signals having time variant spectra. |
