“离散时间傅里叶变换”教学方法探讨

离散时间傅里叶变换是数字信号处理课程中重要的教学内容之一，本文利用ZT和离散时间傅里叶变换之间的关系来探讨离散时间傅里叶变换的教学方法。几年的教学实践表明，运用该教学方法进行“离散时间傅里叶变换”的教学，可以收到较好的教学效果。

Discussion on teaching of discrete time fourier transform

Discete Time Fourier Transform（DTFT） is one of important teaching content in the course of i°Digital Signal Processingi±, this paper discusses the methods of teaching and learning based on the connection of Z transform（ZT） and DTFT. Teaching and learning practice show that the proposed teaching and learning methods in learning process have good effects.
