JusticeForPorygonWhy the duck do cars still have analog speedometers? Surely digital ones would be more accurate and much easier to read without looking away from the road for too long.
NakedmoleBecause analog sensors are more accurate than digital ones and that is because they are analog. While an analog system has unlimited resolution, digital systems require a quantization of the sensor data and that is a clear disadvantage when it comes to precision.
PeriodicallyPedanticThere are a whole bunch of problems with this:
- most of the sensors are digital
- the guages are getting their signals from the ECU computer, which is a digital signal
- the guages in your car are not $10000 scientific equipment, they’re not that precise.
- the design of these analog guages means that most precision would be lost just due to human vision.
There are good arguments for analog guages in cars, but precision isn’t one.
Interesting! Thank you!
