Direct Digital Synthesis (DDS)

Direct Digital Synthesis (DDS) is a method for generating precise, tunable electronic signals—like radio waves—using digital data. It involves creating a digital representation of a desired waveform, which is then converted into an analog signal through a digital-to-analog converter (DAC). This allows for rapid, accurate frequency changes and high signal quality, making DDS ideal for applications such as communications, testing, and signal processing. Essentially, DDS provides a flexible way to produce stable and adjustable signals by synthesizing waveforms digitally before turning them into real-world analog signals.
