MATLAB仿真软件在《信号与系统》课程教学中的应用

An Application of MATLAB Simulation Software in Signal and System Teaching

《信号与系统》课程中的理论知识极其抽象,在教学中可借助MATLAB仿真软件强大的数据处理及图形功能将其直观化。为阐明MATLAB仿真软件在《信号与系统》课程教学中的应用过程,以RLC电路构成的低通滤波器为例,说明了MATLAB仿真软件的使用方法,给出了在《信号与系统》课程教学中应用MATLAB仿真软件时一般应具有的主要环节和步骤,从验证理论、加深理解、纠正错误、参数调整、探索规律等方面说明了MATLAB仿真软件的作用。实践证明,将MATLAB仿真软件用于《信号与系统》课程教学可以起到激发学习兴趣和提高教学效果的作用。

For the problem of abstract theoretical knowledge in Sgnal and System, the powerful data processing and graphical capability can be used to visualize the theoretical knowledge. In order to clarify the application process of MATLAB simulation software in teaching of Signal and System, the low pass filter of RLC was taken as on example, the method of using MATLAB was introduced, the main steps of application were given, and the function of MAT- LAB was illustrated from the aspect of checking theory, deepening understanding, putting error right, tuning parame- ters, searching regular pattern and so on. It was illustrated that the learning interest and teaching effect could be im- proved when the MATLAB simulation software was used into the course teaching of Signal and System.
