Heya,
I'm following http://www.irf.com/product-info/audio/classdtutorial.pdf as a guide to design my own Class D audio amplifier for at home fabrication.
Can anyone explain exactly what modulation factor represents in PWM modulation. I just assumed it defined the percent of intended signal you can actually produce in the given modulation scheme. That being said, I can't figure out exactly why it impacts the breakdown voltage for the MOSFET bridge so much?
Any ideas or references would be groovy, I'm new to Audio.
Cheerio,
James
