多课程融合的“信号与系统”实验教学改革

The Reform of Experimental Teaching for the Course Signals and Systems Based on Multi-course Fusion

为了学生更好地理解基本概念和提高综合实践能力,同时加强与相关课程的联系,作者提出了一种多课程融合的"信号与系统"课程实验教学方法。这种教学方法融合理论与实践、软件与硬件,以及其他课程(如"电子测量与电子电路实验""电子电路基础""数字电路与逻辑设计"和"C语言编程"等)的知识。论文通过一个教学案例探讨了多课程融合的"信号与系统"实验教学方案设计和教学实践情况。教学中利用Matlab和Filter Pro等软件对实验原理进行仿真分析,硬件实验采用了美国德州仪器(TI)公司的TIVA Cortex M4 TI模拟创新实验套件。教学试点结果表明,通过以上教学方法的改革加强了课程间知识点的联系,激发了学生的学习兴趣,提高了学生的实践和创新能力,教学效果得到学生的认可。

In order to enable students to understand the basic concepts better,to improve their comprehensive practical ability and strengthen the links with related courses,an experimental teaching method for the course Signals and Systems is proposed based on the multi-course fusion. This teaching method combines the teaching contents of theories and practices,software and hardware,as well as the related curriculum,such as Electronic Measurement and Electronic Circuit Experiment, Fundamentals of Electronic Circuits, Digital Circuits and Logical Programming, C Language Programming. This paper investigates the design of experimental teaching scheme of the course Signals and Systems based on multi-course fusion and the teaching practices via a teaching example. The experimental principle is analyzed based on the simulation using the software of Matlab and Filter Pro. TIVA Cortex M4 TI analog experiment kit is exploited in our experiment. The result indicates that this teaching reform can enhance the links between courses,arouse the learning interest, and improve the practical ability and creativity of students. The teaching effect is accepted by students.
