Line 18: 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).
