调幅

Amplitude modulation

振幅調變

Amplitude Modulation (AM), also referred to as amplitude modulation, by changing the output signal amplitude, to achieve the purpose of transmitting information. Generally, the amplitude of the high-frequency signal output at the modulation terminal is a function of the original signal, demodulates the demodulation terminal and outputs the original signal. The actual function relationship is generally proportional. The biggest advantage of this modulation is the modulation and demodulation is very simple, only need a diode and a capacitor can, of course, the biggest drawback is the distortion is relatively large, while more sensitive to interference, relatively speaking, is a relatively old technology The However, the technology does not mean that the application is not widely used, is still in many areas of application, such as radio (medium wave radio) and aviation radio, especially in the field of aviation radio, the aircraft's speed is very fast, fighter faster, , The Doppler effect is too large, will affect the communication, and amplitude modulation from the Doppler effect, it can not be replaced. At the same time there are some improvements in the amplitude modulation technology, such as single sideband modulation (also known as single side band), residual sideband modulation, and amplitude modulation variants such as the current widely used in mobile communications, multi-amplitude digital modulation. ... 振幅調變Amplitude ModulationAM),也可簡稱為调幅,通过改变输出信号的振幅,来实现传送信息的目的。一般在调制端输出的高频信号的幅度变化与原始信号成一定的函数关系,在解调端进行解调并输出原始信号。 实际上的函数关系一般是正比关系。这种调制方式的最大好处是调制和解调非常简单,只需要一个二极管和一个电容器即可,当然最大的缺点是失真比较大,同时对干扰比较敏感,相对来说是一种比较古老的技术。不过技术古老并不表示应用不广泛,目前仍然在很多领域应用,如收音机(中波广播)及航空無線電,尤其在航空無線電的领域,飞机的行进速度非常快,战斗机更快,对调频而言,多普勒效应太大了,会影响通讯,而调幅不受多普勒效应的影响,故无法被取代。同时调幅也有一些改进的技术,如单边带調變(又稱單旁波帶)、殘邊帶調變,以及调幅的变种如目前在移动通信广泛使用的多幅度数字调制等。...

Definition of 调幅 in the Chinese dictionary

Amplitude Modulation The amplitude of the carrier wave is modulated by the amplitude of the modulated signal. The carrier amplitude modulation wave amplitude modulation. Half of the difference between the maximum amplitude and the minimum amplitude of an amplitude modulated wave and its half percentage is called "amplitude modulation amplitude." 调幅 载波振幅按调制信号振幅而变化的调制方式。载波经调幅后成为调幅波。调幅波的最大与最小振幅之差的一半与其和的一半之百分比称为“调幅度”。
