[sdiy] Terminology Question

[Scott Gravenhorst]

I should know this, maybe my 51 year old brain just can't find it in all
the rubbish up there...

When an analog to digital converter is used to acquire, say 4 samples, and
the samples are summed and then divided by 4, what is the term that
describes this technique (to reduce noise and provide a more accurate sample) ?

Thanks.
