Seismic data processing using digital signal analysis techniques
This paper summarizes some of the unique features of the digital signal analysis techniques used to process seismic acceleration data and provides examples of the results. First an overall description of the automated package is presented. The package consists of several programs and routines that process the acceleration waveforms to enhance signal-to-noise ratio, filter, integrate, perform spectral computations, etc. Next, we discuss some specific problems and solutions associated with integrating the acceleration data twice to produce displacement waveforms and hodographs. A frequency domain integration scheme is described. Finally, we describe a system for archiving the inputs and outputs of the automated package. The archives provide an extensive data base of ground motions from underground nuclear explosions. 7 refs., 8 figs.
