Paper Title:
Compensation Design of CIC Decimation Filter for Seismic Prospecting
  Abstract

In seismic prospecting, the over sample combined with low quantity is used to converter input analog signals to 1-bit data flow. In order to realize decimation filtering for the high speed low resolution signal produced in the process of seismic prospecting, the CIC decimation filter is introduced into seismic survey system to achieve decimation and filting. The principle and the shortcoming were analyzed; finally an ISOP filter is introduced to compensate the pass-band attenuation, Simulation showed it could improve the performance of CIC filter, the cascade of CIC and ISOP is suitable for seismic prospecting system.
