Fourier Transforms, Hermite functions, which form an orthogonal basis of ., are eigenfunctions of the Fourier transform. In Sect. 2.3, we present the Poisson summation formula and Shannon’s sampling theorem. Finally, two generalizations of the Fourier transform are sketched in Sect. 2.5, namely the windowed Fourier transform and the fractional Fourier transform.作者: Transfusion 時間: 2025-3-22 04:24 作者: 環(huán)形 時間: 2025-3-22 04:57
