Dr. Berns, Thanks very much for your reply. I was hoping that it would be a common enough task so that LabVIEW might have something along these lines already done. As you say, once the math is figured out, I'm sure I can get it implemented in LabVIEW. It's the math that I need help on.
I think I found the text you referenced <a href="http://www.amazon.com/exec/obidos/tg/detail/-/0023548568/qid=1084411777/sr=8-1/ref=sr_8_xs_ap_i1_xgl14/102-3789695-1693725?v=glance&s=books&n=507846";>here</a>. Can you confirm that this is the text you are talking about? Thanks for your advice. Tim
