Abstract阐述了两种DDS的原理,频率合成方式(DDFS)和直读方式(DDWS),给出了FPGA实现方式,分析了DDS的几个关键的技术指标,并通过Matlab仿真。频率合成方式是比较常用的DDS产生方式,对它做了详细的原理性介绍和实现说明,重点通过仿真详细对比了两种实现方式在性能指标上的优劣,为后人的选择提供技术参考。
Other AbstractThe principle of two kinds of DDSs(DDFS and DDWS) is elaborated.The implementation mode of FPGA is offered.Several critical qualifications of DDSs are analyzed and simulated with Matlab.The principle and implementation of DDFS are introduced in detail since DDFS is widely used to generate DDS.The advantages and disadvantages of the two implementaion modes are compared with their qualifications.Those qualifications can be used for reference for someone who works in the field of DDSs.
