Abstract

In recent years there has been a great surge of interest in the geophysical industry in the digital processing of seismic data. This activity involves the application of statistical methods of analysis of time series. In a way it is a part of the general subject of communication theory. However, the direction this work has taken is in many respects quite divergent from communication theory as it is used in the communications industry. The divergence is so great, in fact, that if it were not for a small group of workers in this field in the early 1950's, it is doubtful whether we would today be in a position to do what is now rapidly becoming standard operating practice in the geophysical industry.
