    Hi,

    I would like to trace the bode diagram (amplitude and phase) after calculating transfert function between an input and an output signal.

    How can I do that with flexpro 8 ?

    Thx for help

    You can calculate the phase response and the amplitude response with the Fourier Cross Spectral Analyis Object (Spectral Analysis Option). Select your input and output signal in the object list and choose New|Spectral Analysis|Cross Spectrum. Choose the Spectral Procedure Transfer Function and the Spectrum Type Amplitude or Phase. After that you could create a 2D-Diagramm with the amplitude response and the phase response.
