摘要
讲述了在宽带中频数字化接收机中的带通采样及抽取技术。通过具体的例子 ,分析了带通采样定理 ,多级抽取的应用及 H SP5 0 2 14 B数字下变频器各级抽取因子和滤波器设计思路 ,用软件无线电的思想构造了一个数字化接收机的试验平台。
This paper describes the application of band pass sample and decimation in wide band digital intermediate frequency receiver In the digital receiver, we introduce the use of programmable digital down converter (HSP50214B),and bring forward a solution of filter design and multidecimation quotiety
