frequency modulation

基本解释

Frequency modulation does not allow static to creep in .
頻率調制不允許靜電乾擾混入。

The gods who have been in charge here for this last period of evolution use frequency modulation and do not allow freedom of choice.
已經充滿這裡的衆神爲這最後周期的進化使用頻率調整竝且不容許自由選擇。

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?
不僅如此，它還能夠讓我們把頻率調制直接插入到聲音層次之間。現在播放一段示例吧？

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.
