Hi.
I am a new user of LabView..
I want to determine the time delay between two similar signals, (the values of the signals are record in .tdms file) . I am using cross correlation but the time delay vary a as a function of time (and time delay can be positive or negative) . So Cross correlation can't determine the time delay, it found 0 seconds if I use all the data.
So I want to discretized the cross correlation for different interval of the data (containing a defined number of points), in order to have an ~instantaneous~ time delay as a function of time. I don't know how is it possible..
About the cross correlation, I don't understand why is it exceed 1 whereas X and Y (input variables) are <1 (the signal are normalized).??
Thanks a lot for help!
