摘　　要：论述了利用FPGA开发DDS函数发生器的总体设计思路,讨论了任意波形产生、双路移相输出、PWM调制波产生等方面的设计方法。系统基于Altera公司的Cyclone系列FPGA,配合Atmel公司高性能AVR系列单片机实现。In this paper, the design ideas of how to develop a DDS waveform generator with FPGA, including the method of generating arbitrary waveform and how to get two independent signals, are introduced. This system is mainly controlled by FPGA of Ahera. It and is also assisted by micro-processor Atmega64.

关 键 词：直接数字频率合成 FPGA 脉宽调制 任意波形 移相
