针对《数字信号处理》课程理论抽象难懂、工程实践性强、学生水平参差不齐的特点,以MATLAB的GUI为工具并结合FPGA,设计了一个分层式综合实验系统。该系统包含了验证型、综合型、工程实训型3个层次的实验。系统可满足不同层次学生的需求;将抽象的算法直观地演示出来,加深学生对理论的理解和掌握;通过完成FPGA工程性实验,提升学生的工程实践能力。实践结果表明,该系统有助于学生更好地理解课堂所学理论知识,形成硬件设计思路,取得了较好的教学效果。

The characteristics of Digital Signal Processing course are that the theories are abstract,the engineering practices are strong,the students′ performances are uneven. In response to the above characteristics,by using MATLAB GUI tool and combined with FPGA,a comprehensive experiment system was designed based on the integration of demonstration,layering and engineering. The system includes three levels of experiments:verification,application,and engineering training. Taking into account the differences in students′ abilities,the system can meet the needs of students at different levels;it combines abstract algorithms with practical applications to deepen students′ understanding and mastery of theory. Through the completion of FPGA engineering experiments,the engineering practice ability of students can be improved. The practice results showed that the system has assisted the students in mastering the class theoretical knowledge effectively and forming the hardware design thinking;therefore better teaching effect was obtained.
