无载波振幅和相位调制正在成为事实上的标准，迄今已占了这个新生市场的大部分。
Carrierless Amplitude and Phase Modulation has emerged as the DE facto standard, having captured most of the nascent market to date.
幅度调制是用调制信号去控制载波的振幅，使其随调制信号线性变化，而保持载波的频率不变。
Amplitude modulation is to control the amplitude of signal carrier and make it change linearly with modulation signals and maintain its frequency.
用于无线电传输时，信号用载波传送，通过改变(调制)载波的振幅、频率或间隔来实现。
FOR radio transmission, inFORmation is imparted to a carrier wave by varying (modulating) its amplitude, frequency, or duration.
对载波中的信息进行压缩的编码方式可以是载波或周期的频率调制或振幅调制。
The coding used to impress information on the wave can be a function of the frequency (the number of waves or cycles per second) or amplitude of the waves or cycles.
振幅调制分为4种方式：AM(普通调幅)、DSB(抑制载波双边带调幅)、SSB(单边带调幅)、VSB(残留边带调幅)。
Amplitude modulation is divided into 4 ways: am (amplitude), DSB (bilateral with carrier suppression modulation), SSB (single sideband modulation), VSB (VSB).
