摘要
在研究DDS算法的基础上,结合SOC控制技术,设计了一种实现高精度和高稳定度的亚音频输出系统.该系统结构简单,可靠性高,操作简单,可广泛应用于无线电通信的各种场合.详细介绍了DDS算法和硬件设计原理,给出了电路原理图,软件设计原理及流程图.
On the basis of researching DDS algorithm, connected with the technology of SOC, it designs a inferior audio frequency out-put system of high accuracy and high stability. The structure and the operating of this system are simple and the reliability is high.And it can widely used on kinds situation of no-line transmitter-receiver telecommunication. This article introduces the algorithm ofDDS and the principle of hardware design in detail and gives out the circuit diagram,the principle of software design and the flowchart.
