数字信号处理综合实验设计探讨

Design of comprehensive experiment in digital signal processing teaching

根据数字信号处理课程的特点和Matlab在该课程教学中的优势,结合实例探讨了该课程综合实验设计的理念方法,该方法要求学生根据实际需要利用Matlab设计滤波器,并实现对被噪声污染信号的滤波处理。该类综合实验能够将本课程的主要知识点贯穿起来,即有助于对旧知识的复习和巩固,更有助于培养学生综合运用知识解决实际问题的能力,实现了学与用的承接,在教学中取得了较好的效果。

According to the characteristics of digital signal processing course and the advantage of matlab in digital signal processing teaching,the design method of comprehensive experiment in digital signal processing teaching is proposed.This method asks students to design a filter and filter the signal which polluted by noise.The comprehensive experiment can not only help students to understand,but also use the knowledge which has been learned,and the teaching effect is good.
