Need Help with improving peak detection

[Xtasy]

Hello all,

I am trying to improve the results I obtain from the peak detection function by writing an algorithm that looks at the array of locations outputted by the peak dectector. The true/desired  peaks our data will always have a difference/period of around 7 seconds between the next good peak, therefore, any detected peaks that are closer together than approx 7 seconds should be removed. Writing this algorthim is proving to be quite tricky. Does anybody have any recommendations of how to go about this and how to implement this within LabVIEW?

Kind Regards

It might be helpful if you posted what you have already tried, along with some typical data.  We cannot make specific recommendations without more information.

It seems that you have two separate problems. First is identifying one true peak. The second is to restrict the examination of data for subsequent peaks to 7 second periods.

How different are any false peaks in shape, amplitude, duration, or frequency from the true peaks?
