第三课 晶体管及其基本电路
现在，晶体管是电子技术中最重要的器件。它们不仅作为独立元件， 而且在集成电路微薄的硅片上可包含成千上万个晶体管
晶体管由3层半导体材料构成:一种类型的薄层在中间，两边分别是另 两种类型。可以有两种排列方式:N型在中间，P型在两边(PNP); P型在 中间，N型在两边(NPN )。中间层称为基极，两边外层分别称为发射 极和集电极(如图1-17所示)
电子信息是当今国内外发展最迅速、技术更新最快的工程领域之一， 电子信息专业英语对学习电子信息新知识和新技术起着非常重要的作 用。

digital information signal. In the system shown in Figure1.1(b) analog modulation involves the variation of the light emitted from the optical source in a continuous manner. With digital modulation, however, discrete changes in the light intensity are obtained (i.e. on-off pulses). Although often simpler to implement, analog modulation with an optical fiber communication system is less efficient, requiring a far higher signal to noise ratio at the receiver than digital modulation.

Unit Six Multimedia
So what is multimedia data? Let’s first look at the related notion of media data. McLuhan, in Understanding Media, considers media as “extensions to man”, as technologies and products giving our senses access to further forms of information.[2] This very broad definition encompasses two more specific views. The first relates the term media to how information is conveyed and distributed; for instance, we have print and broadcast media. Second, we also use the term media when describing the materials and forms of artistic expression. This occurs when we speak of digital media, not in the sense of digital storage media, but in the sense of digital counterparts to natural media.

Load in text
• Historically, the linear regulator was the primary method of creating a regulated output voltage. It operates by reducing a higher input voltage down to the lower output voltage by linearly controlling the conductivity of a series pass power device in response to changes in its load. This results in a large voltage being placed across the pass unit with the load current flowing through it. • 在历史上，线性稳压器曾是产生稳压输出电压的主要 方法。通过对级联功率通过器件导电性线性控制以响 应负载变化，线性稳压器将输入高电压降为输出低电 压。这种方法导致在负载电流流经的通过单元两端出 现一个大电压。
