Talk:Oversampling

Typo?
"After being sampled at 800 Hz, the signal could be digitally filtered to have a bandwidth of 100 Hz and then further downsampled to closer to 200 Hz."

Backward compatability
Backward compatability doesn't seem to be working with my various HiFi set-ups. Not sure if this is to do with oversampling or a.n.other it is all rather infuriating not to mention expensive. I wonder what the longer-term solution will be. Znethru

Oversample vs Supersample
Why no mention of "supersampling"? wasn't there a separate page for that before? —Preceding unsigned comment added by Spot (talk • contribs) 00:15, 14 July 2008 (UTC)


 * I added a Supersampling link to the See also section. ~Kvng (talk) 20:02, 15 April 2020 (UTC)

Unclear
"For instance, to implement a 24-bit converter, it is sufficient to use a 20-bit converter that can run at 256 times the target sampling rate. Averaging a group of 256 consecutive 20-bit samples adds 4 bits to the resolution of the average, producing a single sample with 24-bit resolution."

I am no expert or engineer, but the abovementioned statements are unclear and seemingly contradictory. Does it mean running 256 x the target sampling rate (sentence 1), or simply running 256 20-bit samples then averaging it out? They are not the same. 116.14.16.166 (talk) 02:30, 12 April 2010 (UTC)
 * I agree. --ANDROBETA (talk) 09:01, 17 October 2010 (UTC)


 * To help us improve this, please explain where specifically you see an internal contradiction. It is talking about running at 256 x target sample rate then averaging those in blocks of 256 samples to produce samples at the target rate. --Kvng (talk) 15:09, 17 October 2010 (UTC)


 * It could be either 256 20-bit A/D running in parallel at the sampling rate, or 256x the sampling rate with 1 A/D.


 * I think this potential ambiguity is adequately addressed in the current text. ~Kvng (talk) 20:02, 15 April 2020 (UTC)

Oversampling and colour handling
Hi! I'm a dumb end-user of old analog video game console scalers. I read that some scalers use oversampling in order to achieve a pseudo-4:4:4 processing. I don't really undertstand what it means in simple English, and I don't know what it implies when the analog source already exhibits signs of chroma subsampling. Some paragraphs about that in the article would be appreciated. Please. 😅 -Philippemorin123 (talk) 19:08, 20 December 2022 (UTC)
