频率调制

调频英语:Frequency Modulation,缩写:FM)是一种以载波的瞬时频率变化来表示信息的调制方式。(与此相对应的调幅方式是透过载波幅度的变化来表示信息,而其频率却保持不变。)在模拟应用中,载波的频率跟随输入信号的幅度直接成等比例变化。在数字应用领域,载波的频率则根据数据串行的值作离散跳变,即所谓的频率键控(FSK)。

调频技术通常运用在甚高频段(VHF无线电波段)上的高保真音乐和语音的无线电广播。普通的(模拟)电视的音频信号也是透过调频方式传递。窄带形式的调频广播(N-FM)限于商业上的声音通讯和业余无线电领域,广播中使用的调频技术则一般称为宽带调频(W-FM)。

Frequency modulation 频率调制

A signal may be carried by an AM or FM radio wave.
FM has better noise (RFI)  rejection than AM, as shown in this dramatic New York publicity demonstration by General Electric in 1940. The radio has both AM and FM receivers.  With a million volt arc as a source of interference behind it, the AM receiver produced only a roar of static, while the FM receiver clearly reproduced a music program from Armstrong's experimental FM transmitter W2XMN in New Jersey.
An American FM radio transmitter in Buffalo, NY at WEDG

In telecommunications and signal processing, frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. This contrasts with amplitude modulation, in which the amplitude of the carrier wave varies, while the frequency remains constant.
