| Abstract: | This thesis carries out a study on the application of Matlab minimum phase filter and uses reverse conjugate array method to devise the filter. Through the record of the filtering processing in the shadow zone of Taiwan by Hefei Seismic Station, the filter lowered the noise interference of the ground movement and highlighted the features of the seismic signals. It provides good help for the analysis of earthquake and achieves good effects. |
