Exactly! And under that lens all fundamentals applying to analog also apply to digital: that they are inherently unstable and that noise will always win in the long run.
Which sounds at the very least imprecise to me, considering that I'm writing it on a digital (and therefore analog) computer.
- ajb 3y agoIn fact, Von Neumann proved mathematically that it's possible to build a reliable system out of unreliable components. But, modern digital logic uses a simpler mechanism: the thing you are missing is that noise does not propagate or accumulate in discretize (digital) systems, as long as it remains below a threshold, and circuits are designed so that it is far below the threshold.
