Of course you haven't. Everybody should know that the zeros travel faster than ones because they are lighter. It is just common sense. :) Seriously, you should Google on "intersymbol interference." What happens when a digital signal (a square wave) travels down a wire is that the sharp corners get rounded. This rounding is not symmetrical. The back of the pulse drops off quickly, but the front of the pulse has a gentler decline. So it looks like the "holes" (the zeros) are being filled in by the front of the one pulse. So it looks like the one is catching up with the zero. ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
