数字化地震记录资料中包含了大量的干扰信号，影响资料分析处理，有时还造成波形不完整或严重变形，很难进行深入的分析。利用MATLAB设计数字滤波器对不同记录中的干扰波进行滤波，达到消除干扰的目的。实例表明，此方法具有良好的效果。

Lots of disturbance signals such as low-frequency components and high-frequency ones contained in the digital seismic records often lead to the distorted or incomplete seismic waveforms, which are difficult for the seismologists to analyze. On the basis of MATLAB software, the authors developed digital filters to eliminate the disturbance signals in the digital seismic data recorded by Tengchong earthquake station. The filters is proved to be practical.
