摘要
针对数字信号处理课程学时有限、学生层次差别大、实验内容缺乏工程背景的特点,以Matlab的GUI作为开发工具,设计了一个分层-工程-演示一体化的综合实验系统。该系统功能强大、交互性好、操作简单,能够完成基础性、拓展性、综合性、工程性4个层次的实验。它可以适合不同层次的学生需求、将抽象的理论与工程实践相结合,使大量抽象的算法以更加直观的形式表现出来,易于学生的理解和接受,是一个教师辅助教学、学生拓展实验的好平台。该平台将传统的实践教学拓展到课堂,实现了传统教学模式的转变。实践证明,该系统不仅大大地改善了教学效果,而且也激发了学生的学习兴趣,提高了学生的工程实践能力。
According to problems of course of the digital signal process that the class hour is limited, the students have multilayer, experimental content lacks engineering background, by using Matlab GUI tool, a comprehensive experiment system is designed based on connection of layering, engineering and demonstration. The system has powerful functions,good interaction and simple operation. The basic, extending, comprehensive and engineering experiments can be completed by this system. Accordingly, the system can be suitable for the needs of different levels students and combine abstract theory with engineering practice, so that a large number of abstract algorithms are intuitively and easily understood by students. Therefore, this system is a very good teaching platform for teachers and experiments platform for students. The platform extends the traditional experiments to the classroom teaching and realizes the transformation of the traditional teaching mode. Practice has proved that the system not only greatly improves the teaching effect, but also stimulates the interest of students, improves the students' ability of engineering practice.
