No electronic component, especially no analogue electronic component, is actually a mathematically ideal implementation of its nominal function.
Where did you find that? I found it for the first time this year.
It's not only not an ideal implementation, but also an unintentional implementation of other components
i.e.. a resistor is also a capacitor and an inductor, and might even make a good RF antenna.
It matters more as the frequency becomes higher.
Digital electronics, in most part, you can ignore that except for the supporting analogue
jargon making something work. Clock crystals and their capacitors oscillation for example.
I can't convey audio that I can hear over the net to show what I want to show you,
but it's actually about an Amiga emulation on a PC that lacks Amiga characteristic after the digital output at least.
