The Implementation of Parallel Sweep DDS Based on FPGA
Han Chen · Public Communication of Science & Technology · 2010
In this paper we firstly introduce the concept, architecture of the Direct Digital Synthesizer. Then Base on traditional serial DDS,a parallel architecture DDS wich frequency sweep function was bring forward , Finally the theory simulation and hardware implementation was given for the parallel structure of DDS, higher output signal can be obtained base on this parallel DDS architecture in condition of lower DDS system clock。
