摘　　要：探索数字信号处理课程的实验教学平台建设,提出了三种实验教学平台建设方案。基于MATLAB软件的实验教学平台和基于CCS软件的实验教学平台,按照实验教学内容,在MATLAB软件平台上编写MATLAB脚本实验程序,在CCS软件平台上编写C语言实验程序,组成实验教学程序库,参考该程序库完成实验教学。基于MATLAB软件和DSP实验箱的实验教学平台,结合实验教学内容,编写MATLAB脚本程序和C语言程序,组成实验教学程序库完成实验教学。借助三种实验教学平台,以FFT快速算法和FIR带阻滤波器设计及其滤波分析为例,讨论了其实验方案及其步骤,比较实验结果,可以看出,三种实验平台都能较好地完成数字信号处理课程的实验教学。This paper aims to explore the experimental teaching platform of the digital signal processing courses and proposed three construction plans for these platforms,namely the experimental teaching platform based on the MATLAB software and the experimental teaching platform based on the CCS software.According to the experimental teaching content,the MATLAB script experimental programs is designed based on the MATLAB software platform,the C language experimental programs on the CCS software platform.These programs constitute the experimental teaching program library used to complete the experimental teaching.The experimental teaching platform based on the MATLAB software and the DSP experimental box can write the MATLAB script programs and the C language programs according to the experimental teaching content and constitute the experimental teaching program library to complete experimental teaching.With the help of the three experimental platform and taking the FFT Algorithm and the FIR band-stop filter design and filtering analysis as an example,this paper discussed the experimental plan and steps.And by comparing the experimental results,it found that the experimental teaching of digital signal processing courses effectively can be completed by the three experimental platforms.
