Are we talking audio signals only? If not, there are plenty of natual or man made signals that are not continuous by definition and are measured as such, and i would not call them digital either. Reasons being, for instance but not only, that not all values are allowed. For instance in mass spectrometry (hint: spectrometry not spectroscopy precisely as a consequence of being a result of counts, not a continuous wave). Another example everyone knows is the ionizing radiation, commonly measured in counts per unit of time.
I have no clue of electronics, but i have the feeling that digital as used in audio might imply some sort of coding? (It is a question)
In any case, i think that the definition as chosen by Amir in the video is spot on for the purpose of explaining that the signal can get noise or whatever, all this discussion is just.... a forum discussion
