WebThe Fourier Analysis tool calculates the discrete Fourier transform (DFT) or it's inverse for a vector (column). This tool computes the discrete Fourier transform (DFT) of the given vector (column) using the Cooley-Tukey decimation-in-time radix-2 algorithm. The vector's length must be a power of 2. This tool can also compute the inverse discrete Fourier … WebSep 9, 2009 · Jetzt hast du die Information im Frequenzfenster. Die Information über die Phasenlage ist bei dem Zugbeispiel natürlich bedeutend, kann evtl. bei anderen Beispielen aber vernachlässigt werden. Ein weiteres Beispiel für die Nutzung der Fouriertransformation (bzw. Fast Fouriertransformation = FFT) ist ein Stimmgerät für eine Gitarre.
