Rick Actually, you can't even get a "pure" sine wave. A "pure" sine wave is found only as a mathematical abstraction. Any real sine wave you find will not be pure, if you examine it closely. That was my point. The original request was from someone who wanted his work done for him without having to think about it. So the only coorect answer is that what he wanted simply can't be done. If he was willing to spend some of his own time thinking about it and using resources that are available online (including some on my web site), he might find that what he *really* needs can be done with some effort. But I doubt that he'll have too many people volunteering to do it for him. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
