Abstract [en]

This paper describes a new digital data acquisition system that can be used to record signals from infrasound events. The system includes a QF4A512 programmable signal converter from Quickfilter Technologies and a MSP430 microcontroller from Texas Instruments. The signal output of the infrasound sensors is converted to digital via a 16-bits Analog to Digital Converter (ADC). To prevent errors in the conversion process, Anti-Aliasing Filters are employed prior to the ADC Digital filtering is performed after the ADC using a Digital Signal Processor, which is implemented on the QF4A512.
