Oversampling input

Oversampling, a.k.a. supersampling, refers to fetching more samples than you need.


This usually implies you are using and ADC to give fewer but stabler samples than that it actually runs at.


This is useful for a few different but related reasons.


Avoid aliasing, and/or easier input filtering

Imitate higher resolution, and lower noise
