Sigma delta modulation is the most popular form of analog-to-digital conversion used in audio applications. They are also commonly used in D/A converters, sample rate converters, and digital power amplifiers. This workshop will discuss methods of operation, design, and use of sigma delta modulators. The theory behind their operation will be introduced and explained. We will discuss the issues with their use and how they can be resolved. We will explain how their performance is assessed and how best to navigate through the specifications on a sigma delta modulator’s data sheet. Finally practical examples will be given to illustrate the concepts presented.
