To use digital seismograms economically and effectively, it is essential to know the purpose for which the seismic data are to be put into digital form. In the digitizing process, a large number of options are available. Proper choice of these options can easily make a 10 to 1 or even a 100 to 1 change in the overall cost of processing.

Digital seismic records can be used effectively with large-scale computers to perform virtually any type of linear or non-linear filtering, correlation, weighted stacking, or statistical analysis. Experimental procedures commonly are performed most economically in the digital domain.
