在接收信号的数字化、软化的实现中,数字下变频起着重要的作用。本文首先介绍了数字下
变频的组成结构,然后详细分析了数字下变频的工作原理,描述了在实现数字下变频时,设计方案所
采用的高效滤波器———CIC 滤波器和多相抽取滤波器的结构和原理。最后,用通过Simulink 对数字
下变频的性能进行了仿真。在仿真的基础上使用Insight 公司的FPGA 开发系统,用测试电路实测了
数字下变频的性(In the receiving digital signal, softening the realization, the digital down-conversion plays an important role. This article first introduced the digital down conversion of the composition, and then a detailed analysis of digital down conversion of the working principle described in the realization of digital down conversion, the design used in high-performance filters--- CIC filters and multi-phase extraction filter structure and principle. Finally, with the adoption of Simulink for digital down-conversion performance of the simulation. In the simulation based on the use of Insight s FPGA development system is measured using the test circuit of the digital down-conversion of)
