From Euler's formula :$w(n)=\; \backslash frac\; \backslash ,w\_r(n)\; -\backslash frac\; e^\}\; w\_r(n)\; -\; \backslash frace^\}\; w\_r(n)$ Due to the basic properties of the Fourier transform, its spectrum is :$\backslash hat\; (\backslash omega)\; =\; \backslash frac\; \backslash hat\_r\; (\backslash omega)\; -\; \backslash frac\; \backslash hat\_r\; \backslash left(\backslash omega\; +\; \backslash frac\backslash right)\; -\; \backslash frac\; \backslash hat\_r\; \backslash left(\backslash omega\; -\; \backslash frac\backslash right)$ with the spectrum of the rectangular window :$\backslash hat\_r\; (\backslash omega)\; =\; e^\}\; \backslash frac$ (the modulation factor vanishes if windows are time-shifted around 0) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hann function」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
