| Abstract: | The mechanism for short wave radio station to disturb seismic instruments has been analyzed in this paper.It is pointed out that the interference is due to the entrance of seismic instruments.Having used low pass network by means of the interference free theory combining practical station condition,the effect of rejecting interference is obvious. |
