| Abstrakt: | A PC-based field recording system has been employed to record broad-band seismic data. These portable stations were powered by solar panels and batteries and utilized data compression. In order to improve the dynamic range of the 8-bit recording system analog data compression was used and this improved the recording dynamic range from its nominal + or - 42 db to about + or - 84db. Decompression of the data was done under software control. [ABSTRACT FROM AUTHOR] |
