摘　　要：在"信号与线性系统"课程中,傅立叶级数和傅立叶变换是一个非常重要的内容,通过这些内容的学习,学生可以建立起信号频谱的概念,同时也可以理解线性系统的频域分析方法。本文针对学生在求解一个关于傅立叶变换的问题时出现的困惑,首先给出了问题的最佳答案,然后分析了问题的本质,最后给出了该问题的最优解法。In the course of Signals and Linear Systems, Fourier series and Fourier transform is an important content. Through the study of these contents, students can obtain the concept of signal spectrum. They can also understand the method to analyze a linear system. Focus on the puzzlement of the students occurs in solving the problem of Fourier transform, this paper firstly gives the best answer. The author also studies the essential of this problem, and finally gives the optimum solution.
