Deconvolution typically is implemented with the least-squares-error criterion, although other error criteria also can be used. Deconvolution requires a model that describes the internal structure of a seismic trace. More exactly, *deconvolution* is based on the assumption that a seismic trace can be represented as the *convolution* of a reflectivity series with a seismic wavelet. This so-called convolutional model of the seismic trace leads directly to the method of deconvolution, in which we attempt to recover estimates of the reflectivity series from the recorded seismic trace.
