Aug 26, 2012 · A common reason for upsampling is rate matching, for instance mixing two signals with different sample rates, or sending different lesser rates of audio to a player that only plays at …

Mar 1, 2016 · How does "up-sampling" differ from "over-sampling"? I thought the two terms were synonymous, but others have told me this is wrong.

Nov 20, 2017 · Upsampling is lossless when the factor is an integer (taken you also remember the factor), but some information is lost when the factor is not an integer. Upsampling could theoretically …

Oct 3, 2023 · A low-passed signal, bandwidth limited to 4KHz is originally sampled 10 KHz. If I want to resample it at 20 KHz, I take these steps. Are these correct? Am I missing an step? First we need to …

Nov 30, 2020 · 2 Downsampling reduces dimensionality of the features while losing some information. It saves computation. Upsampling brings back the resolution to the resolution of previous layer. My …

All upsampling methods follow the same basic scheme: Insert zeros between samples: These results in a periodic repetition of the original spectrum but leaves the spectrum in the original band completely …

Apr 1, 2019 · Perhaps I need to learn more about digital sampling itself, but I just can't fathom what upsampling is supposed to do? Like from 44.1 to 192 gets me what exactly in the end?

Dec 25, 2019 · In U-nets I would like a more straight-forward/detailed explanation in how the upsampling part ("right part of the U") is performed. I read that it can be done by "transposed convolution layers" …
