I totally agree. It's not like with analog where minor changes affect in minor ways. It's been encoded, and if the information isn't right, it won't be decoded correctly and you get nothing (or something horribly wrong).

As an example (and this is overly simplified), what if I want to send 67. In binary, that's 1000011. Now, if the signal gets delivered wrong, who's to say how bad the outcome will be. If I read 1000001, then I get 65. Not too bad. If I read 11000011, then I get 99. Yowza. If I read 0000011, then I get 3. Oops. With a digital singal, minute changes cause both big and small changes.
