DDS Using the Arduino
Instructive experiments with simple hardware
The principle of direct digital synthesis, or DDS, is used in practically every item of communications, RF or audio test equipment available today. The potential for extremely high frequency resolution, the ability to program the output waveform, and the fact that the output frequency can be changed essentially instantaneously, all make DDS an attractive alternative to a PLL frequency synthesizer.
