modulation is the transmission of information to be loaded onto a high-frequency signal in the process.amplitude modulation using signal to control the rate of carrier,with its linear modulation signal changes,and maintain the same carrier frequency.in the amplitude modulation,in accordance with the strength of signals in the spectrum of different components,it is divided into ordinary am (amplitude modulation standard am),with inhibition of bilateral carrier am,the carrier single sideband suppression am.the main difference is the different methods and structure of the spectrum.

摘 要：调制是将要传送的信息装载到某一高频信号上去的过程。振幅调制是用调制信号去控制载波的幅度，使其随调制信号线性变化，而保持载波的频率不变。在幅度调制中，根据已调信号的频谱分量不同，分为普通调幅、抑制载波的双边带调幅、抑制载波的单边带调幅。它们的主要区别是产生的方法和频谱结构不同。

The results show that injection locking synchronization is realized when injection rate is large enough. In the injection locking regime, similarity index is larger for external modulation than that for direct modulation. If injection rate keeps unchanged, synchronization is little affected by modulation index, but it is affected by modulation frequency. Since outputs of the master laser are antiphase for direct modulation and external modulation, the fluctuations of similarity index with modulation frequency for the two lasers are contrary.

研究结果表明：当注入强度足够大时，系统实现注入锁定同步，外部调制的相似指数大于内部调制；注入强度恒定时，同步品质几乎不受调制指数的影响，而受调制频率的影响；由于内部、外部调制引起主激光器的输出反相，两种调制方式下同步品质随调制频率的变化趋势也相反。

In order to bring about the spatial depth resolution of the image data obtained, the method according to the invention comprises the following steps: an electromagnetic wave is beamed onto the surface of a photonic mixed element comprising at least one pixel, the pixel having at least two light-sensitive modulation light gates Gam and Gbm and associated accumulation gates Ga and Gb; modulation light gate voltages Uam and Ubm, which are configured as Uam=Uo Um and Ubm=Uo-Um, are applied to the modulation light gates Gam and Gbm; a direct voltage, whose magnitude is at least the same as that of the total of Uo and the amplitude of the modulation voltage Um, is applied to the accumulation gates Ga and Gb; the charge carriers produced in the space charge region of the modulation light gates Gam and Gbm by the incident electromagnetic wave are subjected, as a function of the polarity of the modulation light gate voltages Uam and Ubm, to the potential gradient of a drift field and drift to the corresponding accumulation gate Ga or Gb; and the charges qa and qb which have drifted to the accumulation gates Ga and Gb, respectively, are diverted.

为了使得采用这样一种方法获得的图象数据具有空间深度分辨率，按照本发明的方法包含下述步骤：使电磁波成束在至少包含一个象素的光混合元件的表面上，该象素至少具有两个光敏调制光门G am 和G bm 以及相关的累积门G a 和G b ；将调制光门电压U am 和U bm 施加到调制光门G a 和G b 上，而调制光门电压的构成是U am=U o U m，U bm=U o -U m；将直流电压施加到累积门G a 和G b 上，而直流电压的幅度至少与U o 和调制电压U am的幅度的总和相同；使由入射电磁波在调制光门G am 和G bm 的空间电荷区中产生的载流子经受漂移场的电位梯度，并漂移到相应的累积门G a 或G b ，而电磁波是调制光门电压U am和U bm的极性的函数；已经分别漂移到累积门G a 和G b 的电荷的方向反向。

amplitude modulation：调幅

至于调变的方案主要分为调幅(Amplitude Modulation)和调频(FrequencyModulation)两种. 一般来说,调频技术比调幅技术更能有效扺抗噪音的干扰. 这里提醒大家,很多遥控机师都有一个误解,认为调频发射器和调幅发射器是互不干扰的. 这个观念是绝对错的!

amplitude modulation：振幅调制

A超是振幅调制(Amplitude Modulation)超声诊断仪的简称,其工作原理如下:A超在超声波探头中仅仅使用一块石英晶体,向动物体内发射超声波,碰到声阻抗不同的组织时,发生反射,反射回来的超声波又被探头吸收.

amplitude modulation：振幅调变

主题内容:振幅调变(Amplitude Modulation)即射频载波(Carrier)的振幅大小随着调变声频信号电压的大小而成正比例变化的一种调变方式. 一般,载波为较高频的射频信号,而调变信号为较低频的声频信号.

amplitude modulation：幅度调制

AM 幅度调制 (Amplitude modulation)-----由载波信号的幅度变化代表信息的一种调制方法. 参见modulation. Application layer (应用层)-----OSI参考网络模型的第七层,向OSI模型之外的应用程序 (如电子邮件或文件传输)提供服务.
