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 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 a labview block diagram to do filtering(windowing functions) on the signals in frequency domain, and then transfer the signal back to time domains.
which provides parameters to calculate the length and the other characteristics of the transmission line (this part could be done anyway outside labview, the labview is mainly to function IFFT and result time domain signal data as output). And later on, we could compare some conclusions by using different frequencies between the...
