Whole document tree 14.7. Fourier Analysis ToolThe Fourier Analysis tool normally performs a Fast Fourier Transform to obtain the discrete fourier transform Fs of the given sequence ft of real numbers according to the formula given in Figure 14-27. Select the "Inverse" option to calculate the inverse discrete fourier transform ft of the given sequence Fs of real numbers
Specify the cells containing the datasets in the "Input Range" entry. The entered range or ranges are grouped into sequences either by rows or by columns. If you have labels in the first cell of each data set, select the "Labels" option.
