说明：  基于matlab实现的双线性变换法设计滤波器，对心电图滤波，得出幅频特性图(Matlab based on the realization of the bilinear transformation method designed filter, for filtering electrocardiogram obtained amplitude-frequency characteristic map)

能够很准确的计算单输入单输出系统的信噪比。(Very accurate calculation of the SNR of the single-input single-output system.)

地震波处理软件，加速度处理信号，可以直接得到频谱描述。(Seismic processing software, the acceleration signal processing, which can be described directly by spectrum.)

介绍如何用matlab设计fir滤波器，很详细！！！！！！！！！！！！！！！！！(A great progress in the discipline of digital processing is the research on design method of digital filter. FIR digital filter plays a significant part in the processing of digital signal because it can realize linear phase so conveniently that the group delay doesn’t vary with frequency. In the modern electrical system, the FIR digital filter is applications for its good linear phase character.)
