Hello, my name is weiwei.
Here is my question.
I am currently using auto power spectrum VI to apply the frequency analysis on the wave I obtained. The output of the auto power spectrum VI is frequency interval and the amplitude of wave in frequency domain. In my case, my frequency interval (delta(f)) is 100 [Hz] and I have 5000 sampling points for the wave in frequency domain. If I want to obtain the freqeuncy at each sampling points, I am confused with the value I should start with. Should the first sampling point be 0 or 100 [Hz]?
If the first sampling point is 0, then the last one represents 499900, which is quite weird and there shouldn't be amplitude at 0 [Hz].
I attach the photo of my program in this post.
