Design of FPGA-based Arbitrary Waveform Generator

The article introduces how to achieve the arbitrary waveform generated system based on the single chip using Direct Digital Synthesis(DDS)technology,whose core module-DDS is realized by FPGA chip.The waveform generated system can produce many kinds of waveforms.The waveforms are of high-frequency resolution,wide bandwidth,while achieving phase regulation functions.This article mainly introduces the design of the system core module,and gives specific theoretical and experimental data analysis conclusions.
