Line 18 ⟶ 20: what does "local model" means in the option 2 section? --[[Special:Contributions/190.60.93.218\|190.60.93.218]] ([[User talk:190.60.93.218\|talk]]) 18:53, 29 May 2014 (UTC) == Entropy is not reduced == Hello, the statement "because the entropy of the difference signal is much smaller than that of the original discrete signal" is wrong. The idea of a DPCM is to reduce the variance by building a difference signal. The entropy is not reduced (it is not changed at all by calculating the difference signal). Entropy is only reduced in the quantized signal (obviously). <!-- Template:Unsigned IP --><small class="autosigned">— Preceding [[Wikipedia:Signatures\|unsigned]] comment added by [[Special:Contributions/130.75.31.216\|130.75.31.216]] ([[User talk:130.75.31.216#top\|talk]]) 09:21, 20 August 2018 (UTC)</small> <!--Autosigned by SineBot-->
