realtime fft

[Yves]

Hi
is it possible to do a "realtime"-fft on LV6? I mean, to do a data acquisition (not a sinus-function, just normal sensor data) and see the fft-spectrum and the frequencies and the different modes.
is there an example somewhere.
thanks for your help.

There's lot of examples. Just go to Help>Find Examples>Analyzing and Processing Signals>FFT and Frequency Analysis. There's one called Simple Spectrum Analyzer.vi that's written for use with a daq board. I won't get into a discussion of "realtime" but it does do a continuous power spectrum.
