Hello,
I am using the Time Domain Peak Detector in Labview 6.0 to scan through a signal. My data are fairly noisy, and have the potential to generate false positives. However, the signal I am looking for (actual ocean waves with a ~10sec period), I am able to define a threshold and width that get rid of most of the problems. Occasionally, though, I end up with lots of false positives (detecting peaks where none exist)... most puzzling is that these can occur very close to each other (i.e. 4-5 peaks within a time period shorter than the width I have defined). Does anyone know what might cause this or ways to avoid it? In practice, it isn't a big deal, since I can then throw out any waves shorter than width, but it is an extra step in an already slow process (running the Peak Detect vi is already 1/2 the time involved in this program).
Thanks for any suggestions.
Mike
