MATLAB辅助的“信号与系统”理论教学研究
|
摘要
"信号与系统"课程在理论教学中存在着许多要点和疑难问题,尤其是信号卷积、系统时域响应以及频域响应等部分,数学公式复杂,理论性太强,学生难于理解掌握。结合MATLAB通过举例介绍MATLAB在理论教学中的具体应用,帮助学生完成信号计算以及系统分析的可视化仿真,使学生既正确理解相关理论知识,又培养了学生的信号建模及编程能力。实践表明该教学模式能有效提高学生的学习积极性和主动性,为后续课程的学习打下良好基础。
There are many key points and difficult problems in the theory teaching of signal and system course, especially in signal convolution, time domain response and frequency domain response. The mathematical formula is complex and theoretical, which makes it difficult for students to understand and master. Combining MATLAB and theoretical teaching to improve teaching effect is a hot topic. This paper introduces the concrete application of MATLAB in theory teaching by some examples, and helps students to complete the visual simulation of signal calculation and system analysis, it not only enables students to understand the relevant theoretical knowledge correctly, but also cultivates students' signal modeling and programming ability. Practice shows that the teaching mode can effectively improve students' learning enthusiasm and initiative, and lay a good foundation for the follow-up courses.
