提出了一种基于FPGA的数字下变频器实现方案 ,在这一方案中采用硬件描述语言 (AHDL)描述数字下变频器的内部逻辑结构 ,并且具有微机接口 ,可以与微处理器相连接。
A scheme of digital down converter based on FPGA is proposed. In this scheme, the hardware description language (AHDL) is used to describe the internal logic structure of the digital down converter and has a microcomputer interface to connect with the microprocessor.
