direct digital sythesis Direct digital synthesis for accuracy and stability direct digital synthesis (dds) is a technique for generating waveforms digitally, using a phase accumulator, a look-up table and a dac the accuracy and stability of the resulting waveforms is related to that of the crystal master clock.

Direct digital synthesis (dds) is a method of producing an analog waveform—usually a sine wave—by generating a time-varying signal in digital form and then performing a digital-to-analog conversion because operations within a dds device are primarily digital, it can offer fast switching between output frequencies, fine frequency resolution.
