摘要
该文给出了一种基于FPGA的数字调制器实验模块的设计方法,该实验模块能实现10种不同的调制,同时还可作为由MCU控制的任意波形发生器。介绍了FPGA实现数字调制器的原理,在完成DDS模块基础上,给出了多种数字调制器的实现方法,最后对系统功能和性能进行了测试,测试结果满足设计要求。
This paper presents a design of digital modulator based on FPGA. The modulator can not only realize ten kinds of modulation, but also perform as an arbitrary waveform generator controlled by MCU. The basic principle of digital modulator is first introduced. Then, after the realization of DDS model, the implementation of digital modulator is discussed. Finally, the functions and performance of system are tested, and the results validate the approach.
