PWM is not digital. PWM is in pulses but that does not make it digital.

Sorry. I was stating that PCM is better than MPEG. Compressed signals
can be in PCM. I was comparing WAVE files to MP3 files. In my
experience WAVs are better than MP3s.

Makes me wonder what PCM video would look like if compared to the
crappy MPEG stored on DVDs. DVD video is certianly better than the
video you get in those VHS cassettes. However, if only DVD used the
visual equivalent of .WAV audio, it would be much better in picture and
color resolution. DVDs do use PCM audio, which is fine, but it is time
they start implenting their video in PCM and stop their useless MPEG
video.
