利用MATLAB信号处理工具箱SPTool完成地震资料滤波处理

摘要

The paper introduced how to use signal processing tool box SPTool to design digital filter and showed the processing effect of seismic data by using instance. The instance demonstrated that SPTool is easy to operate and can design all kinds of filter according to the demands of seismic station , which has good practical value.%介绍如何利用MATLAB信号处理工具箱SPTool设计数字滤波器，并用实例给出地震资料滤波处理效果。实例表明， SPTool信号处理工具箱操作简单，并能够根据台站的需要设计各种滤波器，具有很好的实用价值。
