FX-decon and two-dimensional deconvolution produce similar results with similar computer time requirements. The two-dimensional deconvolution filter might allow more flexibility in controlling the action of the process than is allowed with FX-decon. For example, the range of dips passed by two-dimensional deconvolution might be controlled by the shape of the filter. Two-dimensional deconvolution appears to have some advantage over FX-decon since two-dimensional deconvolution does not produce the artificial lineups along strong signals to the extent FX-decon does. Two-dimensional deconvolution also does a better job of removing random noise.
