FREQUENCY MODULATION在英语中的意思是什么？

调频

Frequency modulation

在电信和信号处理中，频率调制是通过改变波的瞬时频率来编码载波中的信息。 在模拟信号应用中，载波的瞬时和基频之间的差异与输入信号幅度的瞬时值成正比。 数字数据可以通过在预定的一组频率之间移动载波的频率，通过载波进行编码和传输 - 这种称为频移键控的技术。 FSK广泛应用于调制解调器和传真调制解调器，也可用于发送摩尔斯电码。 Radioteletype也使用FSK。 频率调制用于无线电，遥测，雷达，地震勘探，并通过脑电图监测新生儿的癫痫发作。 FM广泛用于广播音乐和语音，双向无线电系统，磁带录音系统和一些视频传输系统。 在无线电系统中，具有足够带宽的频率调制在抵消自然发生的噪声方面具有优势。 当载波相位调制是FM信号的时间积分时，频率调制被称为相位调制。

In telecommunications and signal processing, frequency modulation is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. In analog signal applications, the difference between the instantaneous and the base frequency of the carrier is directly proportional to the instantaneous value of the input-signal amplitude. Digital data can be encoded and transmitted via a carrier wave by shifting the carrier's frequency among a predefined set of frequencies—a technique known as frequency-shift keying. FSK is widely used in modems and fax modems, and can also be used to send Morse code. Radioteletype also uses FSK. Frequency modulation is used in radio, telemetry, radar, seismic prospecting, and monitoring newborns for seizures via EEG. FM is widely used for broadcasting music and speech, two-way radio systems, magnetic tape-recording systems and some video-transmission systems. In radio systems, frequency modulation with sufficient bandwidth provides an advantage in cancelling naturally-occurring noise. Frequency modulation is known as phase modulation when the carrier phase modulation is the time integral of the FM signal.
