How does volume control work in digital devices?
In: Engineering
The same way it works on analog devices, it increases/decreases the amount of current that makes it to the speaker. This makes it vibrate more or less.
The only difference technically is that digital systems work by steps, while analog is analog. If both had the same arbitrary scale of 1-10 (there is no standard for what a 10 in volume means) then digital generally isn’t programmed to do 8.5, but analog you could set it there.
