Hi everybody
it's my first time on this forum; i read several post about FRF before write mine, but i still got some doubt..
I have to study the dynamic-linear component of a DUT (with black-box approach) and i need to plot the FRF (both amplitude and phase) of the DUT and then i need the transfer function of the DUT. The system is excited with a linear sine sweep controlled via labview and physically generated by an external AWG. I am stop at this point, as you see in my .vi (the input and output signal come from a MOTU so i need to use the "Acquire Sound" VI); how can i find the transfer function from the amplitude and phase plot?? Have you any suggest or example???
Thank You
