modulation signal frequency

基本解释

Also, the effects of the interference group-delay and modulation signal frequency are discussed.
分析了主通道群延迟与调制频率对对消比之影响。
The prerequisite of actively mode-locked fiber laser stable work is that the modulation signal frequency must be the integral multiple to the cavity resonance frequency.
但由于主动锁模光纤激光器腔内有较长的光纤，而光纤的长度极易因外界环境的影响而发生漂移，因而调制频率和腔长很难保持匹配。
The arithmetic formulas for sine wave, linear frequency modulation signal, V-style frequency modulation signal, white noise signal, reverberation signal and echo signal are given by their definition.
根据信号类型的定义，给出了正弦信号、线性调频信号、V型调频信号、白噪声、混响和回波信号的合成公式。

AM radio can be sent over larger distances, but the quality of the sound is not as good as a later kind of radio signal processing, called frequency modulation.
