DDS

DDS, or Direct Digital Synthesis, is a method used to generate precise electronic signals, such as radio frequencies, via digital computation. It works by creating a digital representation of a waveform—like a sine wave—using a computer or digital hardware, then converting this digital signal into an analog voltage with a digital-to-analog converter. This approach allows for highly accurate, stable, and easily tunable signals, making DDS common in communications, signal testing, and radar systems. Essentially, DDS provides a flexible way to produce clean, precise signals entirely controlled through digital programming.
