摘　　要：傅里叶变换在信号分析中占据着举足轻重的地位,也是《信号与线性系统分析》课程中的重要学习内容,单位冲激函数是该课程的一个基本概念。本文对该课程中关于周期单位冲激函数序列的傅立叶变换进行研究,给出了教学过程中所遇到的问题的求解,对傅里叶变换及傅里叶级数等内容的教学有积极的指导作用。Fourier transform plays an important role in signal analysis, also being an important content in the course of Signal and Linear System Analysis. Meanwhile, unit impulse function is a basic concept in this course. This paper studied the Fourier transform of the periodic unit impulse function sequence. Moreover, we provided some discussion of the problem encountered in the teaching of this course, which could be an effective instruction manual for future teaching of the Fourier transform and Fourier series.

关 键 词：周期信号 傅里叶级数 单位冲激函数 傅里叶变换 周期单位冲激函数序列
