A Design of AWG Based on DDS Using the SOPC Technique


This paper presents a design of AWG based on DDS and SOPC technique. The DDS's spurious noise and several improving method are discussed. The realization of the DDS with FM and PM on FPGA is detailed. The software development for AWG based on NiosII and the design of analog circuit for signal's output are introduced. The testing result is satisfying
