When we are in first grade, we are told that there's no such thing as negative numbers. It's not a lie, but rather a loving way to limit a complex situation so that those with limited understanding can grow. I believe most people here on comp.dsp realize that is what I am doing here since there are several things in my explanations that are clearly oversimplified. -- % Randy Yates % "My Shangri-la has gone away, fading like %% Fuquay-Varina, NC % the Beatles on 'Hey Jude'" %%% 919-577-9882 % %%%% <yates@ieee.org> % 'Shangri-La', *A New World Record*, ELO http://home.earthlink.net/~yatescr
