| Abstract: | The basic theory of the network analysis in the filter design is introduced in this paper. The interferences sources of soil and rock-work blasting vibration signal at a power station extended project are analyzed and an anti-interference low-pass transmission filter used measuring blasting vibration signal is designed. The result is that anti-interference characteristics is improved in blasting vibration measurement. |
