FFT implementation without using inbuilt FFT function provided with labview

[rita86]

Hi,

I am very new to labview ,I have to implement FFT on NI Node WSN-3202.No fft inbuilt function on WSN target is there to do so.Please anyone give me some idea to implement FFT without using fft function in labview.

Thanks

Hi rita86,

Even tough you are new in LabVIEW I would suggest you start with Wikipedia http://en.wikipedia.org/wiki/Fast_Fourier_transform#Algorithms and have a look at the Algorithms section.

Keep in mind that this will require a lot of math to get it right.

This should be a good starting point but I can't help you with any real code.

Hi rita,

when all you need is "some idea" I would suggest to read the Wikipedia article on FFT...
