What you have said is really informative. Thanks a lot! You suggested not using a window, but if I try without one, the spectrum is crowded without any clear pattern showing up. I think not removing the dc, was the problem why that high value for 0.0033 HZ showed up. You talk about bins here, how do you label the bins here ? How do you seperate them ?
Also, I am using FFT Power Spectral Density.vi for my PSD analysis. This function asks what type of averaging you want to perform, I am going with "no averaging". Am I doing the right thing, or I should choose one from Vector Averaging, RMS averaging or Peak Hold ? And this function also has the Window constants input, and it's optional using it. The question is, in my case, should I use the window constant for noise bandwidth ? Should I really use that ? Thanks & Best Regards,
