摘　　要：在ＣＤＳＮ台站用数字滤波方法对数字地震仪进行抑制噪声滤波，方法简单易行。通过震例检验，把本人新创造的滤波器同ＡＲＳ软件中含有的滤波器相结合，对地震信号的识别有一定的参考意义。The paper describe how to use digital filter to filter off seismic from earth noise in China DigitaI Seismic Network(CDSN).The realizing method is simple and easy. The main point of the method is to apply ARS software to the filter.It can raise sign noise in seismogram and can raise precision of phase,especially the earthquake is weak in intensity.After we keep abreast of new edit filter,then we can filter to any digital seismogram.It is a good assistant for station’s people.
