Digital Seismic Data Representations: Gain-Ranging, Precision, System Response, Seismic and Computer Considerations

Abstract

Because of trends toward increasingly precise analog-to-digital converters, we recommend that the data storage standard for the Seismic Data Analysis Center be a 16-bit word that is gain-ranged or becomes a 32-bit word only when necessary. There is no problem in converting any existing input format to this format. The amount of additional archival storage media used will be insignificant and rapid access can be assured. The primary disadvantage is the complexity of decoding and converting the archival record to a process desirable word.
