摘要
该文给出了一种基于DDS的可变频多路正交信号发生器的设计及原理分析,设计以AT89C52单片机为主控芯片,利用直接数字频率合成器芯片AD9854进行编程及频率改变。在给出硬件设计的同时,对上位机软件及程序进行了说明。
In this paper,the des gn and principle analysis of DDS-based frequency-changed multiplequadrature signal generator is giVen.The design uses AT89C52 micro cdntroller aS the master chip,and take advantage of direct digital frequency synthesizer AD9854 to program and ensure frequency change;Not only given the hardware design,but PC Software and procedures are also described.
