Abstract : When data are digitized, the sampling rate is selected to provide for the highest frequency phenomena predicted. Much of the time the data is of lower frequency, and redundant data is obtained. A technique has been developed to reduce the quantity of redundant data. It has been applied to both short and long period seismic data. Seismograms from before and after processing have been compared to evaluate the effect of the data. A 5 to 1 reduction in data quantity, while maintaining adequate data quality, seems feasible. (Author)
