in reply to How do I find peaks in noisy data?

Hi, To bring 'islands' out of the noise you need to sum the data repeatedly over itself. The islands will become more prominent and you should be able to clearly see them over a threshold. You should also normalise the data first because the noise may be at different levels, spectrum analysis? thats the direction I would try anyway. http://www.dliengineering.com/vibman/spectrumanalysis.htm
