Discussion on Teaching Method of Fourier Transforms Led by Engineering Application
Fourier transform theory is widely used in mathematics,physics,engineering,and other fields.For beginners,the content of Fourier transform is complex,diverse and difficult to understand.The traditional teaching mode is difficult to arouse the learning interest of beginners.In order to solve this situation,this article discusses how to vividly demonstrate the principles and properties of Fourier transform through application examples of one-dimensional and two-dimensional Fourier transform.We demonstrate the application of audio signals in daily life for one-dimensional Fourier transform,and illustrate the theory and value of two-dimensional Fourier transform using image signals as an example,enabling beginners to have a deeper understanding of the essence of Fourier transform theory.
