摘要
角度调制是用调制信号去控制载波信号角度(频率或相位)变化的一种信号变换方式,可以分为频率调制(FM)和相位调制(PM)。信号经过角度调制后,频谱结构将发生变化。
The angle modulation is a way in which modulating signals are used to control the angles of carrier signals (frequency or phase). It can be divided into frequency modulation (FM) and phase modulation (P M). The signal, after the angle modulation, will change in its spectral structure.
