I also know that analog has more information in the sine wave functions and that the digital square forms lose the excess forms in the analog sine waves, thus a form of informational expression is lost to the digital format.
Still, the information is available more discretely in digital, and it may be nominal, yet effective in transcribing the analog into a more effective expression, informationally speaking.
As in AM radio, some of the SIGNAL is lost to white noise, thus the integrity of the signal. That is why FM radio is more likely to keep the signal intact, like a digital expression of the information in the signal.
So, information is digitally expressed as a more successful means of keeping the integrity of that information.
That's all I have on this subject
