Djpark0115 (talk) 07:00, 21 May 2009 (UTC) Q-1 is necessary in the encoder/ecoder diagram of option2 ??Reply

Yes, good catch; it's needed in the type 2 encoder as well. Maybe you can alert the editor who made the figure... Dicklyon (talk) 17:19, 21 May 2009 (UTC)Reply

Please make it more 'audible'

Please explain the roles of Z-1, the circuitry. —Preceding unsigned comment added by Piotroxp (talkcontribs) 06:51, 19 June 2009 (UTC)Reply

Q-1 is horribly wrong! Quantization is not invertible. Option 1 is only possible if no quantization is done and the compression algorithm is lossless.
