numbers are nothing, I can tell you that only the sound that goes out of speaker is valid, and many will tell you "analog is warmer", by warmer meaning sound... I am not a fan of AB, but they could have a point there
Yes, as wwenze says, I'm not talking about performance comparision, but simple figures like the ratio between the number of Class D amplifiers that have been sold last year and the number of Class B, AB...
The reason for asking this is that I have the impression (I might be wrong, of course) that Class D are still not widely known and even less widely accepted. Of course most of you here are as familliar with Class D amps as with your own hands (ok, I might be exaggerating ) but for what I've experience in other "technical circles" it is not the case. Most people I have surveyed have "kinda heard" something about Class D, they know it is a switched amplifier and they thing that D stands for digital... I have checked on internet and I havent found any convincing figures.
Anyway, the topic keeps open...
If PWM today handles and processes the signal in the coded binary state, I might accept that Class D amps are digital too.
Isn't digital defined by info that's carried in binary coded (not incidental) state,
It's how the signal is sampled that matters
FM is a sine-ish wave clipped to look square after the limiter, but it is sampled as analogue.
is voltage ladder ADC considered digital or analogue, sure it is an A-D converter, but instead of just one and zeros it can have values of 2 to 15.
