Thank you, Jerry - sxy6z - 2009-07-04 10:48:00

Would you please clarify it in more detail? Do you mean that the value has
over flow for the Long type (the type of Y(j) is Long)?

i would say the subject line (it looks like you changed it from some
other thread) is not conducive to anyone figgering out what the hell
you be talking about.

Thanks, Jerry!

How happy for you that I still retain a bit of my photographic memory!

I mean that something saturates somewhere if what should be a sine 
becomes square. You need to track down where in your code that is.

Try reducing the amplitude of your signal by some factor -- say, 4, and 
see what that does to the result.
