Abstract: Determining and optimizing the performance of a Class-D audio power amplier can be very dicult without knowledge of the use of audio performance measuring equipment and of how the various noise and distortion sources in uence the audio performance. This paper gives an introduction on how to measure the performance of the amplier and how to nd the noise and distortion sources and suggests ways to remove them. Throughout the paper measurements of a test amplier are presented along with the relevant theory.
