Abstract

The DDS is shown in a simplified form in Figure 2.1. In this chapter the blocks of the DDS are investigated: phase accumulator, phase to amplitude converter and filter. The D/A converter was described in Section 5.4. The methods of accelerating the phase accumulator are described in detail. Different sine memory compression and algorithmic techniques and their trade-offs are investigated.
