To address the exiting problems in the digital signal processing experimental teaching, such as lack of diversity and systematicness, and help students consolidate theoretical knowledge and improve practical ability, the design of comprehensive digital signal processing experiment using Matlab/Simulink was discussed.This comprehensive experiment will help the students not only better understand the basic theory of amplitude modulation/demodulation,but also flexibly use the digital signal processing knowledge such as spectral analysis and filter design to analyze and solve practical problems.What's more, it is helpful to improve the students' interest and enthusiasm to study, ability of independent thinking and innovation.%针对数字信号处理实验课程教学中存在的内容单一、知识点零散等问题,以巩固学生理论知识,提高学生实际动手能力为目的,利用Matlab/Simulink软件平台,对"数字信号处理"课程的综合性实验设计进行了探讨和研究.在课程中引入信号的幅度调制与解调综合实验,使学生在了解调制解调基本原理的基础上,灵活运用所学到的数字信号处理知识,如频谱分析、滤波器设计等分析问题和解决问题,并直观地观察实验结果,以此调动学生学习的积极性、自主性和创造性,达到培养学生独立思考、善于创造、综合应用知识的能力.
