求翻译（电子的~）
Although there are several types of amplitude modulation, AM double-sideband full carrier(DSBFC) is probably the most commonly used. AM DSBFC is sometimes called conventional AM or simply AM. Figure 3-1 illustrates the relationship among the carrier [Vcsin(2πfct)],the modulating signal [Vmsin(2πfmt)],and the modulated wave [Vam(t)] for conventional AM. The figure shows how an AM waveform is produced when a single-frequency modulating signal acts on a high-frequency carrier signal. The output waveform contains all the frequencies that make up the AM signal and it is used to transport the information through the system. Therefore, the shape of the modulated wave is called the AM envelope. Note that with no modulating signal, the output waveform is simply the carrier signal. However, when a modulating signal is applied, the amplitude of the output wave varies in accordance with modulating signal. Note that the repetition rate of the envelope is equal to the frequency of the modulating signal, and the shape of the envelope is identical to the shape of the modulating signal.

翻译包你满意,
Although there are several types of amplitude modulation,AM double-sideband full carrier(DSBFC) is probably the most commonly used.虽然幅度调制有好多类型,但AM双边带全载波（DSBFC）恐怕是最常用的的了.AM DSBFC is sometimes called conventional AM or simply AM.AM DSBFC有时称为常规AM或简称AM.Figure 3-1 illustrates the relationship among the carrier [Vcsin(2πfct)],the modulating signal [Vmsin(2πfmt)],and the modulated wave [Vam(t)] for conventional AM.图3－1示出了用于常规AM的载波[Vcsin(2πfct)]、调制信号[Vmsin(2πfmt)]和被调制波[Vam(t)]之间的关系.The figure shows how an AM waveform is produced when a single-frequency modulating signal acts on a high-frequency carrier signal.该图示出了AM波形在单频调制信号作用在一个高频载波信号上时是如何产生的.The output waveform contains all the frequencies that make up the AM signal and it is used to transport the information through the system.输出信号包含组成AM信号的所有频率,它被用来通过系统传送信息.Therefore,the shape of the modulated wave is called the AM envelope.Note that with no modulating signal,the output waveform is simply the carrier signal.因此被调制波的形状被称为AM包络.请注意,没有调至信号时,输出波形只是载波信号.However,when a modulating signal is applied,the amplitude of the output wave varies in accordance with modulating signal.可是,当加上调制信号时,输出波的幅度就根据调制信号而改变.Note that the repetition rate of the envelope is equal to the frequency of the modulating signal,and the shape of the envelope is identical to the shape of the modulating signal.请注意,包络的重复速率等于调制信号的频率,而包络的形状等同于调制信号的形状.
