General audio topics that don't fit into specific categories.

Um, no.

Digital is not poor capturing signals that are close to Nyquist, AS LONG AS THEY DON'T GO OVER NYQUIST.

But when you vary a signal "close to nyquist" you expand its bandwidth, and you go OVER fs/2 in real spectrum.

Do not forget that the only zero-bandwidth signal is an infinitely long sine wave.

Even a switched sine wave has a heavily spread spectrum. That's all it takes. All. It. Takes.

Btw, I suspect this is a prophead subject. It involves understanding the duality theorem, for instance, to see how mulitplying in the time domain convolves spectra in the frequency domain (never mind what some people seem to think).
