五.

1.虽然直流电是有用的,但它有一个突出的缺点,也就是没有简单而经济的方法来提高或

降低它的电压。而交流电则没有这一缺点。如果使用一种专门的设备,我们就能够把高压

变成低压或把低压变成高压。我们用来改变电压的这种设备叫做变压器。交流电也能容易

地被改变成直流电。能够做到这一点的器件就称为整流器。

2.噪声也许是电子学和电讯工程中每个人必须熟悉的唯一论题,而不管其专业是什么。噪

声总是存在的,它限制了事实上每个系统的性能。同时,对噪声的测量是十分有争议的,

几乎每个人都有一种对噪声及其效应进行量化的不同的最得意的方法。

3.外加有电压的线圈被称为初级,而从中获得感应电压的线圈被称为次级。如果次级的匝

数比初级多,则变压器就称为升压变压器,在这种变压器中次级绕组的交变电压高于加给

初级绕组的电压。如果次级的匝数少于初级,则变压器称为降压变压器,在这种变压器中,

次级绕组的交变电压低于加给初级绕组的电压。在绕制得很好的变压器中,次级电压乘以

次级电流的乘积几乎等于初级电压乘以初级电流的乘积。

4.噪声也许是电子学和电讯工程中每个人必须熟悉的唯一论题,而不管其专业是什么。噪

声总是存在的,它限制了事实上每个系统的性能。同时,对噪声的测量是十分有争议的,

几乎每个人都有一种对噪声及其效应进行量化的不同的最得意的方法。

5.电流有两种:一种是直流电(DC),一种是交流电(AC)。直流电是在导体中总是朝一

个方向流动的电流。交流电则是周期性地改变其流动方向的一种电流。通过输电线输送的

是电流是交流电,这是因为交流电易于控制,且当我们把它输送到远方时比较经济。

6.所谓电路或网络,我们指的是一堆按某种方式相互连接在一起的电器件(例如电压源和

电流源、电阻器、电感器、电容器、变压器、放大器和晶体管)。这种电路的各种用途虽然

重要,但并不是本书主要关心的事。而我们的主要兴趣将是在确定某一特定电路的性能这

一过程(这称为“分析”)方面。
