Wow, you are cool! At first, I am sorry if I wasn't clear enough. It was probably because I didn't understand my problem and LabVIEW exactly.
Anyway, I think what I want looks like (3). However, I would also like to know other possibilities, at least (1). Because I will need it eventually to calculate the energy of my each pulse signal. I appreciate your help. I really mean it. Thanks much. Chunrok Bae
