How to create complex waveforms using fast digital circuits. #electronics

Download this article as a .PDF High-frequency signal waveforms flow through everything from communications systems to sophisticated test systems. They are often generated by analog sources, such as different types of oscillators. In recent years, however, as digital components such as digital-to-analog converters (DACSs) have improved in speed and performance, many signal waveforms can now be created starting with digital code and hardware. Signal generators based on digital architectures may be known as arbitrary waveform generators (AWGs), but they are often called direct digital synthesizers (DDS). They may not be able to match all the performance levels of a good phase-locked analog frequency synthesizer, but they have some benefits in terms of the precision and frequency switching speeds of the waveforms they can generate. In contrast to an indirect analog frequency ...
