Missing context or corrupted paragraph
The paragraph that reads PCM in the late 1940s and early 1950s...a glitch-free Gray code...a fan beam instead of a scanning beam seems to be out of place or unexplained -- did we suddenly switch from audio to video? Also, the name "Goodall" is employed without being explained or introduced.
Nomenclature?
The word pulse in the term Pulse Width Modulation is somewhat confusing, as there appear to be no "pulses" per se anywhere to be found.
I believe this should read 'Pulse Code Modulation'. Please confirm. — Preceding unsigned comment added by Ktims (talk • contribs) 09:37, 21 June 2006 (UTC)
High Definition Media
From what I have read, many Blu-ray movies have PCM soundtracks. But HD DVD? I don't think ANY of my HD DVD movies have a PCM soundtrack. I am not sure "many" applies to HD DVD PCM soundtracks. — Preceding unsigned comment added by 75.71.201.149 (talk) 12:05, 25 October 2007 (UTC)
