安装好FEM后,FEM破解最后版本,呵呵 ,有的问题要注意下. (FEM installed after, FEM crack the final version, huh, huh, and some problems to the attention of the next.)

this code can be used to compute classic harmonic analysis

用MATLAB设计一个低通和带通滤波器,传统的数字滤波器的设计过程复杂，计算工作量大，滤波特性调整困难，影响了它的应用。本文介绍了一种利用MATLAB信号处理工具箱（Signal Processing Toolbox）快速有效的设计由软件组成的常规数字滤波器的设计方法。给出了使用MATLAB语言进行程序设计和利用信号处理工具箱的FDATool工具进行界面设计的详细步骤。(design a digital filter use matlab)

说明：  正弦信号，单个频率的正弦信号，频率为1KHz，幅度为5(Sinusoidal signal, a single frequency sinusoidal signal, a frequency of 1KHz, the range of 5)
