Not really. That the square wave isn't perfect doesn't make it an analog signal.

Since the digital voltage level can’t change instantaneously (a perfect square wave) it bears some resemblance to an analog signal’s infinite voltage levels.

yes, we agree, I am only trying to make the point that the digital signal does not strictly meet the definition of 2 and only 2 distinct states since it takes some time to transition. Like I also said, it really makes no difference to the discussion of whether or not USB sucks = a red herring

Analog information is represented by constantly changing voltage levels with an infinite number of possibilities.That’s a common misnomer. It could only be true if the bandwidth of the analog system were infinite, which is impossible, of course. So just like digital, analog is bandwidth limited. Its resolution is finite.

It is not a misnomer, my statement is absolutely correct. There are an infinite number of voltage levels between any 2 levels. It has nothing to do with bandwidth.
