Implementation of a DDS signal source based on FPGA

DU Bai-sheng

Abstract

A signal generator is designed with the direct digital frequence synthesis(DDS) technology, through the digital controlling the increment of signal phase and a FPGA system.The signal of this generator has many advantages such as convenience for changing magnitude and frequency,high resolution,high frequency changing speed,reducing phase noise.The signal generator has been used in all kinds of applications.
