The Fast Fourier Transform, or FFT, which is based on the Fourier analysis method is an optimised method for calculating the amplitude Vs frequency, of functions or experimental or computed data.
In order to apply this methodology, after selecting the parameters to be analyzed, it is necessary to choose the following parameters:
- number of curves (exp + calc) to be analyzed
- number of time windows to be analyzed
- sampling frequency
- cut frequency
- time begin and time end of each time window.
