CHAPTER 26
Interfacing With the Digital Domain
The advance of digital audio has greatly improved the fidelity of audio storage media and generally made wonderful things possible, but sound waves remain stubbornly analogue, and so conversion from analogue to digital and vice-versa is very necessary. Today’s analogue-to-digital converters (ADCs) and digital-to-analogue converters (DACs) have excellent performance, with 24-bit accuracy at a 192 kHz sampling rate a commonplace, but to achieve this potential performance in an application, a good number of factors need to be appreciated. Some of them, such as the need for effective HF decoupling, are relatively straightforward providing you follow the manufacturer’s recommendations, but others, involving ...
