WebFor comparison, we use the traditional predictive deconvolution to squeeze all wavelets (figure 5a), the filter length N is 10 and the prewhitening factor is 0.0001. The traditional method produces a reasonable result at the high-frequency locations, however, the predictive deconvolution still loses part of the original amplitudes. WebTo efficiently detect the slow Rayleigh wave, three methods based on digital signal processing are proposed: wave shaping, dynamic predictive deconvolution, and dynamic predictive decomvolution combined with wave shaping.

As the input traces have 512 samples, I took the length of the filter equal to 50 samples. The residuals of L 2 and L 1 deconvolution on the pure trace are similar (Figure ). As the input wavelet is minimum-phase, the L 2 deconvolution is efficient. how to silver soul beach house guitar tone
