Embedded Computing Design

In this final part of the series, we will cover how to select the reconstruction DAC and complete the DDFS system.

In part 2, we will cover how to implement a high precision NCO in software. Building a high precision ac tone generator with similar or better distortion performance than the best analog oscillators.

The test and verification of ac performance of high precision fast analog-to-digital converters (ADCs) with resolution better than 16 bits require a near perfect sine wave generator.
