Hi, does anyone read the the manual ? This comes from my on-line help for Fourier[]: - Different choices of definitions can be specified using the option FourierParameters. - With the setting FourierParameters -> {a, b} the discrete Fourier transform computed by Fourier is \!\(\*FormBox[ RowBox[{\(1\/n\^\(\((1 - a)\)/2\)\), UnderoverscriptBox["\[Sum]", \(r = 1\), "n", LimitsPositioning-> True], \(u\_r\), \(e\^\(2 \[Pi] i \( b(r - 1)\) \((s - 1)\)/n\)\)}], TraditionalForm]\). - Some common choices for {a, b} are {0, 1} (default), {-1, 1} (data analysis), {1, -1} (signal processing).
