摘要
从定义和角频率两个角度分析调相,同时从定义和相角两个角度分析调频。进而用数学公式对直接调相和利用调频间接调相、直接调频和利用调相间接调频进行比较,再定量的对调频和调相信号进行比较,从而阐述了调频与调相之间内在的联系。
The paper analyses phase modulation from two angles of definition and angular frequency,and analyses frequency modulation from two angles of definition and phase angle. And then uses a mathematical formula for the comparation between direct phase modulation and indirect phase modulation by frequency,for the comparation between direct frequency modulation and indirect frequency modulation by phase,and then the quantitative comparison of frequency modulation and phase modulation. Then elaborates the nternal connection between FM and PM.
