Hello ,
I am acquiring a train of voltage signals from NI 9225 module placed on a cRIO 9022 controller ( the frequency changes dynamically )
our main aim is to calculate the area of each peak of voltage curve
and have a floating average of the area.
this was partially achieved 
by using a Trigger and gate VI to detect the sample and then integrate it then store it in a array
The problem is the trigger is activated only for the first peak from the original signal hence irrespective of the frequency the value inserted into the array is constant
Is there a possiblity to get the area under each peak ? and update within one second as the waveform gets updated every 1 second.
I tried to use shift registers and loop back the data but i will be calculating the area of the first peak again and again.
below attached is the modified version of the VI, in LV 2013 , and also the image of block diagram.
I request for your sugestions. kindly let me know if i am missing any data.
