A feasibility study of PC-based analog signal processor for marine seismic data acquisition

&nbsp;&nbsp;This paper examines the availability of analog processor for PC to implement the data acquisition system of multi-channel marine seismic survey on a PC base. The analog processor has analog gain and the low cut filtering functions. In this study the data have been acquired by using only the analog gain function. With applying gain function it is observed that the analog signal has the enough energy level and allowable S/N ratio for digitalization. A 2-D seismic section was created using the acquired data and it could be fully utilized for the seismic interpretation.<BR>&nbsp;&nbsp;It can be concluded that the analog processor for PC used in data acquisition system for PC based multi-channel marine seismic survey provides the highly economic and effective survey system.
