WebPredictive deconvolution The problem is now to estimate a predictive filter f with the input traces. 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. 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. polymorphinehttp://sepwww.stanford.edu/public/docs/sep130/intro/paper_html/node5.html polymorphic v tach treatment acls
