Crazy digital audio theories

One has to remember that digital transmissions are engineered to reject noise (RF or other) that may have been injected into the cable. It is a certainty that no perfect square waves are received (or even generated) at either end. Then there may be additional noise coming from the environment that will mangle the perfect square wave some more. This is why there are operational margins in terms of amplitude and time (and shape). As long as the received signal is more or less at the high (or low…
