数字地震监测技术开发与应用论文(二) 一种滤除零点漂移的高通数字滤波器

A kind of high pass digital filter for the reduction of zero drift

总结引起零点漂移的原因,给出了一种可以有效抑制零点漂移的滤波器的指标和特性,使用该滤波器后,TDE-324C地震数据采集器的动态范围得到了有效的改善。

In this paper, we summarizes the cause of zero drift, presents a kind of filter to reduce it. The dynamic range of TDE-324C seismic data digitizer is improved remarkably after using this filter.
