D/A (digital-to-analog) conversion talk typically revolves around getting the 1’s and 0’s from a playback device to your old-fashioned eardrums in one, continuous analog stream of music or whatever. I’ve reached a juxtaposed epiphany about the D/A issue WRT enclosed chairs on wheels: It’s backwards, or upside-down.
ICE (internal combustion engine) cars are digital, and the new stuff is analog. This observation has little to do with the electronics.
Four, six, eight or more distinct power pulses slamming into a crankshaft starts alot of moving parts and noise that are soon to be things of the past, in terms of mainstream transportation. That D/A conversion from the old-school ICE cars is what they are all about, to me. It happens in the seat of your pants and the brain parts connected to your ears during that first test run after washing the black grime off your hands that never seems to disappear from underneath your fingernails.
OTOH, it’s all analog in terms of driving impressions when the rheostats flow the juice. I suppose an argument for electrons bouncing around somewhere could be made. That’s been quite the quandary over the networks since forever. Digital-to-analog conversion is proceeding apace in the automotive industry. Not too sure what to think about it yet, except to say that I’m gonna need a new M-car.
