| Abstract: | How to design the CIC(cascade integrator comb) filter,half band filter and FIR(finite impulse response) filter by use of Matlab was described and a high effective multi cascade decimated filter was designed.The test result showed that this kind of filter can meet the seismic data acquisiting system’s accuracy demands. |
