针对在DSP技术实验教学中存在的问题,提出通过关联学习、对比学习方法来提高DSP技术实验教学效果的设计思路.设计了一种体现教学循序渐进原则的,由系统模块、电源模块、ADDA模块、模拟信号调理模块和通信模块组成的TMS320VC5416 DSP技术实验教学平台,给出了系统设计方案和主要电路,并以一个综合实验作为实例,说明实验教学平台的使用.结果证明,DSP技术实验教学平台符合教学规律和学生的学习习惯,能降低学生学习DSP技术的难度、加快学生掌握DSP技术的速度,具有一定的实用价值和推广价值.
For the problems existed in DSP experimental teaching, an idea of improving the experimental effect is raised based on associating learning and contrast learning. According to the idea, a TMS320VC5416 DSP experiment teaching platform is designed by the teaching principles of step-by-step. The platform is made of the system module, power module, ADDA module, analog signal conditioning modules and communication modules. The system design and main circuit of platform are given. And a comprehensive experiment of the platform is shown as an example. Actual application shows that the DSP technology experiment teaching platform meets teaching laws and habits of students. Tile platform can reduce the diffieuhy of learning about DSP technology and improve the effect of experimental teaching. Therefore the platform has a certain value of practical and promotional.
