peak detection

Hello,

I am currently using Labview 8.0. In that i am facing problems in detecting the peaks of an acquired waveform graph. I tried using the threshold peak detector.vi in the function palette but it doesnot work for me.I also tried filtering the waveform and detecting the peaks but still there was no result. I have uploaded the text file of my waveform here. Can anyone tell me how to detect the peaks of this waveform.

 

Regards,

Nitzy

 I guess the "Peak Detection and Display" example will give you a push in the right direction. But I have to admit I did not look at your example file

Here is some useful tips for the Labview beginner (we have all been there some time)

1)Then starting a new Labview session enable context help (Ctrl+h). Do not be afraid to use the detailed help option

2)Then stuck, go to help in the toolbar then select find examples



Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

why not post a small graph of your data and mark the peak with a grafik tool of your choice and post this picture? 

Posting the data together with a vi to handle it also helps.... 

 

Read the help about peak detector to see what options and parameter you have. 

If you still have trouble to automaticly detect the peak a pre filter might help. 

If you then still get problems, post more information about your setup and I'm shure someone will come up with an idea.

 

In general: Ask yourself how do I detect this peak?  And then try to wire your way.....
