Abstract：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.
