A Multichannel Analog-to-Digital Converter for Seismoacoustic Applications

The authors describe a compact analog-to-digital converter for high-resolution seismoacoustic studies and provide its technical characteristics. The converter has a capacity of 24 bits and 16 channels with the possibility of increasing their number by combining converters into a network. A local Ethernet network is used to exchange data with the control computer, which provides high speed (100 Mbit/s) and interface versatility. Distributed data acquisition systems based on the transducer can be used in surface, borehole, or marine seismic acoustics, as well as in hydroacoustics.
