Zusammenfassung:Measurement of the absolute amplitudes of a seismic signal requires accurate knowledge of the seismometer-digitizer response. When the seismometer and digitizer characteristics are known, deconvolution of the digital system response is relatively straightforward. However, even with a known response, problems in timing and incorrect polarities can often contaminate any calibration parameters derived from these data. When either one or both components of the response for a seismometer system are unknown, the data are often not considered suitable for seismological tasks that require absolute amplitude measurements.
