这是较好的Matlab源代码，希望此代码能对大家有所帮助。(This is a better Matlab source code, I hope this code can be helpful to everyone.)

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)
