modulation signal frequency

基本解释

Also, the effects of the interference group-delay and modulation signal frequency are discussed.
分析了主通道群延遲與調制頻率對對消比之影響。
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.
但由於主動鎖模光纖激光器腔內有較長的光纖，而光纖的長度極易因外界環境的影響而發生漂移，因而調制頻率和腔長很難保持匹配。
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.
根據信號類型的定義，給出了正弦信號、線性調頻信號、V型調頻信號、白噪聲、混響和廻波信號的郃成公式。

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.
