Hello Troy,

I say amazing engineering is the right choice of words. AB+CD is indeed a great design. Although this mean you will have 4x the amount of components. But I don't see how else we can get a working system as reliable as that. I guess it's more suitable if the keeper is going to be away for a long time and there's no one to step in to watch for things.

Afterall, the guy is a professor in Georgia Tech. Georgia Tech is the most respected university for digital signal processing. They were the one the FBI went to for analyzing the Olympic bomber's tape, or that's what our Georgia Tech professors at UBC keep bragging on about. [img]images/smiles/icon_rolleyes.gif[/img]
