realtime analysis

Post by maarcc2050 » Fri Sep 24, 2010 3:54 am

Hi.

Is there a way we could do real time power spectral analysis with activeview? if not, what do people use to do real time analysis with biosemi hardware? By realtime I mean, to see the frequency spectrum in real time. I dont mean to just view the eeg signals but to actually apply some analysis method such as simple fft to view the results in real time as data are streaming in.

Thanks for any pointer.

Certainly, ActiView is written in open source LabVIEW, and you can quite easily add all the real-time analysis you need by adding LabVIEW functions to the diagram (diagram = LabVIEW code). For example FFT is available as standard LabVIEW vi's, see: http://zone.ni.com/devzone/cda/tut/p/id/4541 . Also see http://www.biosemi.com/software_biosemi_analysis.htm (picture at bottom of the page)

Hi Coen

Is this feature of live spectral analysis already exists? (the one in the bottom picture.
How can I get this feature and incorporate it in my Actiview?
Is anyone that made such a feature would like to share it? :)

Thanks a lot
Omer
