What our ears hear as attack, sustain, and decay comes from a sum of many many many different sine/cosine waves. It's a little mind-bending if you haven't groked it before.

Of course, if you add a signal that is, e.g., 2x the Nyquist frequency (one full cycle per sample) then there are some interesting examples: If that high-frequency signal is out of phase with the samples, then without a prefilter you wouldn't see it, and with a prefilter you still wouldn't see it because that content would be filtered out. If it is in phase with the sampling, then without a prefilter, you'd be increasing every other sample and decreasing every other sample, but with prefiltering, it would be rejected and so digitization still wouldn't see it. All of this assumes that your signal is long enough to be considered infinite (or repeating), of course.

It's counterintuitive, but try and think of it like this. You know the input signal (analog) is band-passed to 20kHz, so there are no frequencies higher than 20kHz to be reconstructed. Now look at the 2.2 samples per period; try and draw a continuous line through all the samples without using any frequencies above 20kHz. The maximum frequency of 20kHz limits how "quickly" you can rise or fall the slope of the line. So in fact, there is only *1* solution for the line you draw through the sampling points.

A slightly-shifted sign wave would have around 1 bit of depth, and anything other than a cosine wave has a phase ambiguity (i.e., a cos wave shifted to the right by delta samples the same way a cos wave shifted to the left by delta).

(It shouldn't matter 'cause with even moderate bit depth, the crossing time can be placed to unreasonably good precision. Still, the time at which a step function crosses a given value is strongly a function of the neighboring two samples, so if the signal is sufficiently low-amplitude, you'll run out of bits and stepping either sample by 1 DAC unit would move the crossing by a nontrivial fraction of the sampling period.

I've thought about the same issues in graphics (where at best the reconstruction actually is with square pixels(!)), which has lead me to the Wikipedia [https://en.wikipedia.org/wiki/Kell_factor Kell factor] page, which I haven't heard discussed elsewhere. Now that we have sane resolution on our screens, it would be nice if they included antialiasing filters so we no longer had square pixels (and in particular, so a droplet of water didn't enlarge a pixel and show R/G/B!). It is interesting to note that typically a camera is actually diffraction limited, which introduces a pretty decent AA filter, it's just displays are the problem.
