摘　　要：简单介绍了直接数字频率合成技术(DDS)的组成以及原理,采用VHDL实现了各个模块功能,在QuartusII中完成了设计与仿真。可以输出各种常见波形,并且可以调节波形的频率与相位。下载到CYCLONE器件中,得到所需波形,完成了硬件的仿真。This paper simple presented the theory of DDS technique and how it work. It is designed and implemented by using VHDL hardware description language as design input and the Altera' s Cyclone chip as carrier. It provide different kinds of normal wave- form such as sine wave , square wave, pyramidal wave and so on. The frequency and phase of output signal are adjustable. It has been designed and analyzed in QuartusII software.
