分层递进式“数字信号处理”实验系统的开发与实现

摘要

In view of the students’ differences about source structure and basic level ,one hierarchy and ladder mode is proposed .In this mode ,teaching objectives are clarified into different layers from the simple to the difficult and from the basic to the applicble according to the difference of the students’ ability .Following this principle ,one experimental system based on the digital signal processing is realized using Matlab GUI ,which is divided into the following three sections :foundation ,development and application ,in order that different students can improve their knowledge and abilities .Practice shows that this system is favorable to the students and has obtained the good teaching effect .%针对普通高校生源、学生基础水平存在较大差异的问题，提出一种层次递进式实验教学方案，即根据学生的能力水平设计不同的教学任务，引导学生由浅入深、由基础到应用逐层递进。遵循此原则设计开发了基于Matlab GUI的“数字信号处理”实验系统，分为“基础篇”、“拓展篇”和“应用篇”，以使不同层次的学生在知识和能力上都能得到提高和发展。实践表明，该教学形式深受学生喜欢，取得了良好的教学效果。
