FFT size

[Victor]

Hello all

Just out of interest, what size FFT does Labview do and is it user
adjustable?

cheers

LabView can do any size FFT. Execution is via FFT for power-of-two length input, DFT otherwise. As with most Labview analysis routines, the FFT routine operates on whatever size array is passed as input. (LabView arrays intrinsically pass their length to the callee.)

Thanks a lot.

It's really so obvious now I know.

cheers
