Title The Fourier transforms on �1
Abstract This article mainly introduces the Fourier transform on �� . The first chapter briefly introduces the history of Fourier transforms. The second chapter lists some preparatory knowledge which was required to discuss the Fourier transforms. The third chapter starts to introduce Fourier transform. This paper summarizes the related knowledge of Fourier transform on �1, including the definition of Fourier transform, inversion formula of the Fourier transforms, Fourier transform of convolution and etc. The fourth chapter introduces the related knowledge of Fourier transformation on �2, and the content is corresponding to the third chapter generally. There are similarities and differences between the properties of the Fourier transform on �1 and the properties of the Fourier transform on the properties of the Fourier transform on . The fifth chapter briefly introduces the definition and the related theorem of Fourier transform on �� .There are several examples about Fourier transforms in the sixth chapter.
