Translations:Convolutional model/5/en

The source wavelet does its required job of injecting input energy into the medium. However, its presence on the recorded traces can only cloud the desired subsurface picture. In the final analysis, the effects of the source wavelet usually must be eliminated to obtain a clearer picture of the subsurface. In the mathematical treatment given here, we assumed that the signature wavelet is causal but not minimum phase. In cases in which the source wavelet is known either by direct measurements or by estimation techniques, it can be eliminated by the process called signature deconvolution.
