frequency modulation

基本解释

Frequency modulation does not allow static to creep in .
频率调制不允许静电干扰混入。

The gods who have been in charge here for this last period of evolution use frequency modulation and do not allow freedom of choice.
已经充满这里的众神为这最后周期的进化使用频率调整并且不容许自由选择。

Not only that, it will enable us to insert frequency modulation directly between the layers of sound. Why don't you play a sample now?
不仅如此，它还能够让我们把频率调制直接插入到声音层次之间。现在播放一段示例吧？

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.

One problem is "spectrum incompatibility" among myriad broadband designs--T1, ISDN and nine or so flavors of DSL. Their signals move along copper wire in overlapping frequency and modulation schemes.
FORBES: Magazine Article

a method of transmitting information using a radio-frequency carrier wave. The frequency of the carrier wave is varied in accordance with the amplitude and polarity of the input signal, the amplitude of the carrier remaining unchanged ( abbr: FM)&rarrcompare amplitude modulation

Because the frequency modulation isn’t sensitive with the change of the phase, it can overcome the swift of phase and fading of energy which is caused by water channel.
利用频率调制本身对于相位变换不敏感的特性,抑制了水声信道中多途效应引起的相位偏移以及能量衰减。
