摘要
本文在一维离散Fourier变换定理的基础上,给出并证明了二维离散Fourier变换的几个定理,并将一维离散Fourier变换定理推广到更一般的形式。
On the basis of 1-dimensional discrete Fourier transform theorem, this paper gives and proves several theorems of 2-dimensional discrete Fourier transform and popularizes 1-dimensional discrete Fourier transform theorem to a more ordinary form.
