IIR数字滤波器设计实验教学的探索与实践

Exploration and practice of the experiment teaching on designing IIR digital filter

根据目前数字信号处理课程实验教学大纲和IIR数字滤波器设计的实验教学现状，结合该校“IIR数字滤波器的设计”这一专题实验教学过程中的一些具体做法和心得体会，提出了针对不同专业的学生采用不同的实验教学方法和手段，强调理论与实践相结合，突出这一专题实验的重要性和针对性。实践证明：不同专业学生采用不同的实验手段，不仅能够较快的理解课堂讲授的理论，而且能提高其综合应用能力和分析问题的能力。

According to the experimental teaching scheme of digital signal processing and the present state of the experiment of the designing IIR （infinite impulse response）. Using different experimental teaching ways to design IIR digital filter according to the students＇ majors was put forward. Combining the theory with practice was emphasized, especially the importance of this experiment. The practice proves that when the students with different majors utilize the proper way to the experiment, they can not only apprehend the theory during the class teaching, but also improve their abilities in comprehensive application and analyzing problems.
