摘　　要：针对信号与系统实验环节设置中验证性实验偏多的不足,开展了综合性实验的设计工作,目的是强化学生对基本知识和基本定理的理解并提高学生综合应用所学知识的能力。所设计的综合性实验涉及信号的采集、传输、去噪、滤波、结果展示等多个方面,要求学生利用Multisim、Matlab、Simulink、LabVIEW、Proteus、Keil等常用工具软件进行功能实现。所设计的实验涉及面广,综合训练作用强,受到了学生的广泛欢迎。介绍了综合实验设计过程的设计原则,给出了几个具有代表性的综合实验的实验内容,对示例实验内容的训练效果进行了分析,展示了部分学生优秀作品。增设综合性实验环节后,学生学习兴趣显著提高,对物理概念和基本原理的理解更加深入,取得了良好的教学效果,具有一定的推广价值。The comprehensive experiments for signal and system were designed and carried out to overcome the shortage that there are too many experiments for verification in current stage. The aim is to make students strengthen the understanding of basic knowledge and theorem, and improve the ability to apply what they mastered in their real life. The designed experiments involve sampling, transmission, denoising, filtering and signal exhibition. Students are demanded to accomplish these experiments using Multisim, Matlab, Simulink, LabVIEW, Proteus, Keil or other tool software. The designed experiments cover many aspects, have a strong comprehensive training effect, and are welcomed by students. The designing principle of the designed experiments is introduced. Then, contents of several typical designed experiments are given. Subsequently, the training effects of the typical experiments are analyzed. Lastly, some of excellent works designed by students are presented. After the addition of comprehensive experimental tasks, the students＇ interest in learning is improved remarkably. Meanwhile, students＇ understanding of physical concepts and basic principles is more profound and excellent teaching effect is achieved, and thus the designed experiments have certain promotion value.
