《数字信号处理》课程教学手段的改革与实践

Reformation and Creation of Class Teaching in Digital Signal Processing

介绍了在《数字信号处理》课程中使用了科学计算软件MATLAB语言,对传统教学手段的改革与实践,获得了良好的教学效果。并结合实例阐述了如何利用MATLAB语言强大的计算和绘图功能,实现对连续时间信号的时域和频域分析,以及利用MATLAB中的Simulink仿真工具,以时域抽样定理为理论基础,实时演示如何从抽样信号中恢复连续时间信号。

Abstract： MATLAB, software of advanced scientific calculation has been in use in the course ＂Digital Signal Processing＂. It has turned to be conducive to teaching. With its powerful funcation in calculation and drawing MATLAB is capable of analyzing time range and frequency of continuous-time signals. Based on time sample theorem, we can make use of the Simulink modeling to demonstrate how to recover continuous time signal from sampling signals.
