Frequency spectrum separation

[shjukheter]

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 VI 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.

I am using labview 2011 and i don't find that VI in express pallet.

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

It was joke, the thing about the EXpress VI . 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.
