Hi,
Thank you for the quick reply guys.
However, i dont think i was able to explain myself earlier. My problem at the moment is not really the technical part of "how" to do a certain thing in labview. It is more of a problem with the algorithm.
SO i will try and explain my explain properly.
@Jordan Kuehn: The information you gave was quite helpful. I am actually doing something similar. I am using the peak detector VI and logging time value of each peak. (attached picture VI). But this information is not reliable.
In the files attached with this message, you will see 3 graphs. These are three different measurments taken at exactly same input parameters. But since my signal is an echo, and it is not in an controlled environment right now, as it should be, I am getting variations in each of the three outputs, for exactly the same input.
For eg. Currently if i take the time value of the highest peak as my time value. Then it is not a reliable value because the time at which highest peak occurs changes, even though the input is the same.
Now, I need to develop an algorithm, where i can use certain characteristics or combination of characteristics of the signal (eg. amplitude or peaks or anything else) and measure find a time value which is steady.
I hope I was able to explain my problem better now.
Any help in this direction is highly appreciated.
Thank you infinitenothing and Gary Rubin for your responses.
