Question

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，但楼主能追加点分吗？
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。

Answer 2

虽然有调幅的几种类型，上午双重边带充分的载体(DSBFC)大概是最常用的。 上午DSBFC有时称常规上午或完全上午。图3-1说明在载体[Vcsin (2πfct)之中的]关系调整的信号[Vmsin (2πfmt)]和被调整的波浪[Vam (t)]常规上午的。图显示上午信号波形怎么导致，当一个单频调整的信号在一个高频率载波信号时行动。产品信号波形包含组成上午信号的所有频率，并且它被用于通过系统运输信息。 所以，被调整的波浪的形状称上午信封。注意没有调整的信号，产品信号波形是载波信号。 然而，当一个调整的信号是应用的时，产品波浪的高度变化与调整的信号符合。注意信封的重复率与调整的信号的频率是相等的，并且信封的形状与调整的信号的形状是相同的。

Answer 3

尽管有几种类型的振幅调制,是double-sideband全部载波(DSBFC)可能是最常用的方法。我DSBFC有时被称为或者仅仅是传统是。阐述了数字3-1之间的关系[Vcsin载体(2πfct)],[Vmsin调制信号(2πfmt)]、[Vam调制波(t)]因为传统。这个图展示了如何在一个波形是单纵模调制信号的高频载波信号的行为。输出波形包含所有频率的信号,是,它的作用是通过系统的传输的信息。因此,形状的调制波被称为是信封。注意,没有调制信号的输出波形,仅仅是载波信号。然而,当一个调制信号时,输出波形的振幅调制信号的变化,依照法律、行政法规。需要注意的是,信封的重复速率等于调制信号的频率,和形状的信封是相同的形状的调制信号。

Answer 4

虽然有几种类型的调幅，上午双边带全载波（DSBFC）可能是最常用的。上午DSBFC有时也被称为传统的AM或干脆上午。图3-1说明了承运人之间的关系[Vcsin（2πfct）]，调制信号[Vmsin（2πfmt）]，以及调制波[VA菌根（吨）]为传统的AM。该图显示了一个上午波形产生时，单频调制在高频载波信号信号的行为。输出波形包含了所有的频率组成调幅信号，它是用来运输通过该系统的信息。因此，该调制波形称为上午信封。请注意，无调制信号，输出波形仅仅是载波信号。但是，当调制信号应用，输出振幅随调制信号的规定。请注意，在信封重复率等于调制信号的频率，并在信封的形状是相同的调制信号的形状。
