I am seeking help with an IFFT programming in Labview.
I have testing data from VNAs (vector network analyzer). They are Non-periodic signal in frequency domain from couples of wires used as transmission line. The signals were generated by a constantly varying frequency, started at 9khz and ended at 8.5GHz.and they are in excel form. I also have a programming file in labview, and some formulas that may be needed for the cable length calculation.
I am seeking help from someone whom has knowledge in DSP (mostly about inverse fast fourier transform and the windowing function) and is familiar with Labview. Because I need someone help me to verify the labview programming, and calculate the cable length with clear steps (this part could be done anyway outside labview, the labview is mainly to function IFFT and result time domain signal data as output), that I can use the result to compare to the actual tested cables, and compare the result by using different frequencies between the...
