摘要
Fourier变换是复变函数中一个重要的理论,由于其高度的抽象性使得学生对Fourier变换的概念、性质和应用都缺乏直观的认识和深刻的理解.结合信号与系统和数字图像处理中的实例,开展Fourier变换的工程例证式教学法研究.对于数学专业学生,该方法不仅有助于加深对Fourier变换的理解,而且有利于提升学习兴趣和实践能力.
ion makes students lack intuitive understanding and profound understanding about the concept,nature and application.Therefore,intends to combine the examples in the signal and system and digital image processing,carry out the research on the engineering example teaching method of Fourier transform.For students majoring in mathematics,this method is not only conducive to the deep understanding of Fourier transform,but also helpful to the promotion of learning interest and practical ability.
