Application of DDS/FPGA in Signal Generator Systems
Xiujie Qu · Modern Electronics Technique · 2006
Direct Digital Synthesis(DDS) is a new way to synthesize frequency which is developing quickly these years,and is used in many fields.In this paper,Based on the principle and application of DDS,DDS chip AD9854 is combined with FPGA to develop a kind of signal generator.This kind of signal generator is flexible and controllable,then the user can get several Linear Frequency Module(LFM)signals as needed through choosing different control modules.
