摘要
数字信号处理是用数学方法对信号进行分析、变换、滤波、检测、调制、解调以及快速运算的一门技术学科。该课程的特点是理论性强,计算量大,数学公式及推导过程繁多。针对这一现状,笔者介绍了数字信号处理课程的知识体系结构、各知识点之间的相互联系,指出要正确理解基本概念及定义,并给出了一些改进教学方法的具体建议和措施。
Digital signal processing is a technical subject which uses mathematical methods to analyze,transform,filter,detect,modulate,demodulate and calculate signals rapidly.This course is characterized by strong theory,large amount of calculation,and many mathematical formulas and derivation processes.In view of this situation,the author introduces the knowledge architecture of digital signal processing course,the interrelation between knowledge points,points out that it is necessary to correctly understand the basic concepts and definitions,and gives some suggestions and measures to improve the teaching methods.
