AN2109: The Direct Digital Synthesis Generator

The low-frequency programmable signal generator is proposed. The generator employs the direct digital synthesis (DDS) technique to create an output signal with high-frequency resolution. The PSoC device produces the sinusoidal signal, but other output waveforms can easily be obtained. This design can be embedded in various test and measurement equipment, or be part of other high-frequency generators. The design variances and possible modifications are considered as well.
