How Xilinx DDS Works on an FPGA

This section explains the mathematical principles behind how a Direct Digital Synthesis (DDS) system generates waveforms. It breaks down how phase accumulation, frequency control words, and lookup tables work together to create precise digital signals.

By understanding the equations and relationships involved, the reader can see how DDS converts a discrete-time phase increment into a continuous, stable output frequency with fine resolution and fast tuning capability.
