摘　　要：频率调制技术是在调制过程中使已调信号的频率随调制信号变换,其在军事通讯和生活中等各个方面有着至关重要的作用。本文以调频技术的原理和应用为切入点,利用硬件电路仿真平台Multisim 3.0对基于压控振荡器的调频信号发生器进行了设计和仿真分析。为了得到好的调制效果,利用锁相环路构成一种两点调制的宽带FM调制器,从而获得质量较高的FM信号。本文的研究工作对于实现高稳定性和宽谱调频信号发生器具有重要的现实指导意义。FMtechnology is that the frequency of modulated signal changes with the modulation signal.It plays an important role in military communication and in all aspects of our life.The principle and application of frequency modulation technology are present as the breakthrough point in the paper,following the discussion about the FM process.The FM signal generator based on the voltage controlled oscillator was designed and simulated by using the hardwarecircuit simulation platform Multisim3.0.In order to acquire a good modulation effect,the FMsignal is obtained by usingthe phase locked loop to form a two point modulated broadband FM modulator.The research here plays an important role for the realization of high stability and wide spectrumFMsignal generator.
