Asked by Thomas Schäfer

Hi I would like to perform an inverse fast Fourier transform on a measured set of data recorded with a network analyzer. The data I have is in the frequency domain and I am interested into transforming it to time domain. I have the frequency vector F and the corresponding complex magnitude vector V. I believe that the Matlab function IFFT is the function that I am looking for, but I cannot figure out how to set up the function call correctly. I would appreciate if someone would help me with this. Please let me know if I you need more info of my problem. I do not have access to the signal processing toolbox. Best regards Thomas
