Abstract
This paper presents the concept and design of a digital system to record seismological signals. The hardware and software designed has
been interfaced to the PC 104 BUS architecture in order to achieve a modular system to acquiere, process, record and transmit seismic
data by telemetry. The modularity of this system offers independence technology from the manufacturers of this kind of equipments both
in hardware and software, also because the system was developed under the Linux operating system GNU, which allows easy update of
hardware; the software is an open platform developed in C, which allows the user to configure the system to operate online and updating
according to nedds.
In brief, we propose in this paper a system design option for seismological instrumentation, which presents significant advantages also
for other regions and countries with high seismicity and needs of earthquake monitoring, but have serious limitations in acquiring and
maintaining commercial systems imported from developed countries.
Key words: seismology, instruments, OSSOdas, PC104, Linux GNU, spread spectrum.
