An experimental system was designed with Matlab and ModelSim. This article described how to design a CIC digital filter with MATLAB and implement it with VHDL. The practice indicates that the design of experimental system makes students understand and master the basic theory of the course better, also can improve the ability of students to apply it in engineering.%利用MATLAB和EDA仿真软件ModelSim设计了软件无线电课程实验.对CIC滤波器的MATLAB设计和VHDL实现进行了详细的描述.实践表明,设计的实验内容能使学生更好地理解与掌握该课程的基本理论,并提高工程应用的能力.
