modulation signal frequency

基本解釋

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.
但由于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(huán)境的影響而發(fā)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(jù)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、混響和回波信號的合成公式。

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.
