Fourier Transformation Tool

The "Fast Fourier Transform" (FFT) is an important measurement method in the science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal. Besides, FFT can be applied to data series in order to identify their cyclical pattern and use it for forecasting purposes.

 The Datas’Ok Tool analyzes periodic data by using the Fast Fourier Transform (FFT) option of the MS Excel. It extracts the cyclical component from the data and provides the frequency and magnitude of this cycle(s).
