Frequency spectrum separation

Hello,

             I would like to divide the frequency spectrum for each 1000Hz and would like to see the amplitude levels of peaks in each divided spectrum until 10KHz. How can I do that? Please suggest me some ideas.

You can use the divide and conquer FFT Express VISmiley Very Happy If that VI does not do the job. I have some papers on FFT spectrums that will help you understand the FFT basics. Like how the "frequency bins" are spaced.

Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Sorry my bad, you may not have RISK game add-on Smiley Indifferent

It was joke, the thing about the EXpress VI Smiley Very Happy Smiley Wink. But read the links instead.

I read the document which describes about FFT but how can I separate the each band as I mentioned before. I would like to see the peaks amplitude in each separated band. Please give me some ideas.
