Software function FFT analyzer
The FFT Analyzer module is used to enable the display of the signal in the frequency
range through FFT (Fast Fourier Transformation). Two channels may be operated simul-
taneously. Furthermore, the transmission function between signals can be determined.
The results of the analysis are provided as parameters for further processing. Window
functions (Windowing), Average (average determination) are also provided in this mod-
ule. A signal generator is also integrated for system analysis, which can be fed into the
system by broadband signals, such as white noise, or sine signal generated and through
the parameter interface.
