摘要
针对自适应滤波相关的教学过程中其原理枯燥、内容抽象、难于形象理解的现状,本文提出了一种基于虚拟仪器技术的生物医学信号自适应滤波实验教学系统,该系统可以用形象直观的方式对生物医学信号进行自适应滤波处理并在前面板显示,在背面板可实现相应算法的开发及修改。该系统不但可用于相关实验课程的开设,还可用于相关信号处理算法的研究。
It is known that during the teaching process of adaptive filtering, the principle of adaptive filtering is boring, the content is abstract and the image is difficult to understand. In this paper, a novel biomedical signal adaptive filtering experimental teaching system based on virtual instrument technology was proposed. The system can be used to the biomedical signal adaptive filter processing in an intuitive way and display in the front panel, the corresponding algorithms can be developed and modified in the back panel. The system can be used not only for the establishment of relevant experimental courses, but also for the study of related signal processing algorithms.
