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.
