Hello KB,
my first approach would be:
1) code a subvi giving you a boolean array that is true for "peak" and false for "no peak"
2) create an array for every 3 data arrays
3) AND the boolean arrays
4) now you should have a true for a peak at the same place in all 3 data arrays: discard this data item
You should think about the length of your data arrays (are they all the same length?). To detect peaks you can use a treshold, perhaps using moving average.
Hope this helps,
GerdW
Best regards,
