 Direct digital synthesis

Direct Digital Synthesis (DDS) is a method used in electronic signal generation, particularly for creating precise and adjustable waveform signals, such as sine waves, square waves, or triangular waves. DDS utilizes digital techniques to produce high-frequency signals with high accuracy and stability. Here are the key components and principles involved in DDS: 1. **Phase Accumulator**: At the core of the DDS system is a phase accumulator, which continuously adds a fixed increment to a phase value at a defined clock rate.
