用MATLAB实现滤波器对数字地震资料处理初探

A Preliminary Survey of the Digital Earthquake Data Processing by a Filter with MATLAB

本文介绍了用MATLAB工具软件对数字离散信号进行频谱分析和设计FIR数字滤波器的方法,并用它对数字地震记录进行频谱分析和滤波处理。文中还给出了地震台站测震数据进行频谱分析和滤波处理的实例,对台站在地震数据处理中有一定的应用价值。

This article introduces the methods of the spectral analysis of the digital discrete signals and the design of the FIR digital filter with MATLAB tool software, which is also used for falter processing of the spectral analysis of the digital earthquake record.
