I have a three axis seismometer station and I want to display the ground motion from earthquakes on a computer monitor.
The existing system has an op-amp and filter for each seismometer (for detecting ground motion in the Vertical, North-South, and East-West directions) and an FM telemetry system that connects the station to a recorder via a phone line as shown in that attached diagram.
I'm looking for a way to convert the analog signals (+ and - 5 volts that now go to the recorder) to digital and display the traces similar to an old fashioned seismograph recorder.
The manufacturer of the existing system (Teledyne GeoTech) has a commercially available upgrade, however it is very expensive and I'm looking for a home made solution.
