摘　　要：针对信号与系统以往实验教学中验证性实验比重大、缺乏软件实验、学生主动思考少等不足,开展信号分析综合性探究实验项目实践工作。将关于信号分解、合成、取样与恢复的实验内容有机融合,扩展编制信号分析程序的软件实验内容,把原有三次实验整合为八学时的综合性实验。该实践取得良好的教学效果,具有一定的推广价值。In view of the shortcomings in the previous experimental teaching of Signals and Systems,such as significant proportion of confirmatory experiments,lack of software programming experiments and shortage of students’thinking initiatively,we carried out the practice of a comprehensive and exploratory experiment of signal analysis.On the basis of the original three confirmatory experiments related with hardware operation,the experiments on signal decomposition,synthesis,sampling and recovery are organically integrated.At the same time,the experiment about writing programs related with signal analysis are supplemented,and the original three experiments are integrated into a comprehensive and exploratory experiment demanded to be completed within eight class hours.In general,good teaching effect is achieved and it has certain popularization value with regard to our designed comprehensive and exploratory experiment.
