To implement the DDS Method in software we need four components. The DDS Method (digital direct synthesis). Also in telecommunication the DDS Method is useful for instance in frequency of phase modulation (FSK PSK).
This technique is not only useful for music and sound generation another range of application is test equipment or measurement instrumentation. The frequency range reaches form zero to 16 KHz with a resolution of a millionth part of one Hertz! Distortions can be kept less than one percent on frequencies up to 3 KHz. Almost no additional hardware is required. Here we describe how to generate sine waves with an Arduino board in a very accurate way.
