摘要
通过分析矢量调制器移相的特点,给出了利用矢量调制器实现对输入信号进行移频的基本方法,提出了一种进行连续移频的方案,设计并实现了基于矢量调制技术实现载波移频的控制系统。测试结果表明:该方法控制稳定,移频精度高。
Through analyzing the characteristics of vector modulator shifting phase, this paper gives a basic method to shift frequency using vector modulator,and presents a scheme to shift frequency continuously.At last, a control system using vector modulation technology to realize the frequency shift is designed and realized.The test result shows that the accuracy of frequency shift is great.
