4096 point complex fft

[venki_tav]

how to do fast fourier transform for 4096 point fft complex array.

I have that 4096 complex numbers in xcel.

I know how to read numbers from xcel.

Please let me know how to do complex fft in labview.

Once you have the values as a 1D array of CDB, simply feed it to the FFT from the "signal processing...transforms" palette.

Have you tried? What kind of problems did you encounter?

(Of course you need at least LabVIEW full. LabVIEW base does not do this)
