Perform DFT in LabVIEW

[tintin_99]

Hi , I would like to compute  DFT of a signal. Windowing should also be implemented  to clean leakage from the spectrum. If sample rate is also specified, a frequency vector should be returned. Otherwise, returned frequency vector should be empty.

 I should also be able to return the magnitude of the tone of interest ( specific frequency)

Could you please let me know if I can do it in labVIEW or if there is a block for that?

Thanks

1D FFT

For 1D signals, the FFT VI computes the discrete Fourier transform (DFT) of the input sequence with a fast Fourier transform algorithm.

Will this do what you wnat?
