hello. here i attach with the vi i develop, the subvi, and the offline data. i am doubt that the subvi of "extract portion of signal " or the " numeric integration" has gone wrong. thanks regards Download File:post-5763-1167067021.llb Download File:post-5763-1167067505.vi Download File:post-5763-1167067791.zip

hi i have been getting the analog signal. the analog signal consists of at least 2 curve for each sample. what i need to do is to get the area under these 2 curves respectively. what i did is using basic level trigger to get the 2 location of each curve then extract portion of signal. it works. however, when input to numeric integration vi, it can get the value for the first curve. for the subsequent sample of data, it shows NaN. what;s wrong with that? thanks regards

anyone pls help within one block of data, the basic level trigger can detect the threshold value only once, but my question is how if whithin one sampled of block data , it consists of many curves that i need to detect many index/ time with the same threshold value. thanks regards Download File:post-5763-1166432677.vi
