Class D amplifier basics for DIY audience designers part 1-6

tcrastrs.com In this tutorial, we will cover the most critical Class D design aspects to be able to distinguish between good class D amplifier designs and bad ones. Based on this knowledge you will be able to understand why one eBay class D amplifier model sounds great and others do not.
This tutorial is based on the largest chip manufacturer companies' publicly available applications notes and reference design documents. Most of the good eBay Class D amplifier boards are simplified large manufacturers' reference designs. Special Thank You to International Rectifier/Infineon and Texas Instruments engineers for a well-structured and most completed set of documents. For those listeners, who have an Electronic Engineering background and willingness to study more I added links to source documents at the end of this tutorial.
