数字下变频器在现场可编程门阵列中实现

Implementation of digital down-converter in FPGA

文中提出基于FPGA和分布式滤波器的数字下变频器实现方案,给出各主要功能模块的实现方法,对内部电路原理进行叙述。

In this paper, an implementation of Digital Down-Converter （DDC） based on Distributed-Arithmetic （DA） Filters is presented, the realization of key modules and inner circuit principle of DDC are described.
