摘　　要：离散傅里叶级数及离散傅里叶变换是"数字信号处理"课程中非常重要的内容之一。本文从采样定理的角度出发,利用频域采样方法得到离散傅里叶级数定义,并给出了图形化解释。图形化解释比公式表达更形象直观,期望能够有助于对DFS的理解,能够改善教学效果。Discrete Fourier series and discrete Fourier transform are one of the most important contents in Digital Signal Processing course. From the perspective of sampling theorem, this paper conducts the expression of discrete Fourier series, and supplies the graphical explanation. Graphical manner is more intuitive than formula manner for understanding. This manner is expected to help understanding of DFS, and to increase learning interests and pro- motion of the total teaching effects.
