The disadvantage of such devices is that they can't generate arbitrary waveforms. The idea is that the DDS generates a digital value internally which it then converts to an analog output. They are known as DDS devices, for direct digital synthesis. It was limited to a fairly low frequency by the rate at which the samples could be sent.Īn alternative is to use a component that generates signals directly. The Arduino sent sample values to it, allowing arbitrary wave forms to be generated. In an earlier series of posts, I described building a prototype signal generator using a DAC driven by an Arduino.
