数字信号处理实践教学实例分析

Analysis of examples of digital signal processing teaching practice

数字信号处理是一种应用性很强的技术,是现代计算机、通信、信息、语音、图像、声纳等处理技术的基础。但是《数字信号处理》这门课程的理论性和抽象性都比较强。针对这种情况我们设计一套实践方案,通过让学生对一个实际数字信号的简单处理,不仅增加学生的感性认识,而且还能帮助学生理解和巩固抽象的理论知识。本文主要介绍了上述信号处理的具体实践及操作过程。

Digital Signal Processing （DSP） is not only a kind of practical technique, but also the basis of computer, communications, information, sound, image, and sonar processing. However, the contents of the course, Digital Signal Processing, are very theoretical and nonfigurative. To solve the problem, the author designed a practice project to let students process an actual signal, which could not only give students perceptual knowledge but also help them understand the nonfigurative theoretical knowledge. This paper mainly introduced the practice and actualizing process of the project.
