一个很好的滤波器程序，是用MATLAB编写的M文件，虽然简单，但很有借鉴意义。-a good filter procedure is the use of MATLAB M documents, simple, But a useful one.

结合GA算法实现的双二阶级联滤波器的逆滤波设计，在MATLAB平台实现了简单仿真。(The inverse filter design of double two class combined filter based on GA algorithm is designed, and the simple simulation is realized on the MATLAB platform.)
