摘　　要：本文针对"数字信号处理"课程教学过程中学生对离散傅立叶变换定义、性质以及应用等方面出现的一系列问题,从课堂教学方法改革入手,剖析了常规教学方法中存在的问题,对教学过程进行精心设计,采用了启发式教学、仿真实验等多元化教学方法,达到了启发学生思考、激发学习兴趣、提高学习效果的目的。The Discrete Fourier Transform （DFT） is one of the core contents of Digital Signal Processing course. According to a series of problems appeared in the process of teaching such as DFT definition, characteristic and application, starting from the reform of the teaching methods in the classroom, the problems in the conventional teaching methods are analyzed, and the teaching process is designed carefully. The diversified teaching method including heuristic teaching, simulation experiment teaching is used to inspire students to think, to arouse students′interests in learning and to improve the learning effect.
