| 摘 要： | 在《数字信号处理》课程教学中,傅里叶变换的多种形式及其关联是课程的核心内容。通过对比分析法和图形展示法相结合,对傅氏变换的不同形式进行对比研究,揭示其内部演变规律,并辅以MATLAB软件给出直观演示,使抽象的规律形象的展现出来,从而加深对傅里叶变换以及其在不同形式下关联性的理解,达到了良好的教学效果。

| Abstract: | It is very important to understand Fourier transform in the course of digital signal processing.However,this is difficult to be implemented because of its high abstract characteristics.The paper analyzes the intrinsic relation of the different type of Fourier Transforms,the visual simulation is presented simultaneously.This method makes the abstract theorem intuitive,so it’s easy to learn.The effectiveness in Fourier transform teaching is improved greatly. |
