Unit 4 Integrated Circuit
The development of integrated circuits has revolutionized the fields of communications, information handling, and computing. Integrated circuits reduce the size and the weight of devices and lower manufacturing and system costs, while at the same time providing high speed, excellent functional performance, low power dissipation and increased reliability. ICs are widely used in the electronic industry.

Unit 4 Microelectronics
There are two types of basic integrated circuit: monolithic integrated circuit and the thin or thick film. Monolithic IC are constructed in a single substrate of single crystal semiconductor, usually silicon. Thin or thick films IC are formed on the surface of an insulating material such as glass or a ceramic. Hybrid IC contains more than a single substrate, the term hybrid is also applied to combinations of monolithic and thin or thick film IC.
Unit 4 Microelectronics
Notes ［1］ Intergraded circuits are also classified according to
their functions. Digital or logical IC are used as switches, they are either on or off. In computers the on and off states correspond to 0 or 1.Other IC is called linear or analog IC.

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。

4 Radio and Audio
• 学习重点： • （1）掌握有关调幅、调频、数字无线电广
播、收音机、音频的基本单词、词组和缩 略语的含义及用法
• （2）培养阅读翻译有关调幅、调频、数字 无线电广播、收音机、音频的科技文献和 产品说明书的能力
• （3）学习科技英语中形容词及形容词短语 作后置定语的结构、特点、用法与翻译方 法
翻译：AM广播是使用幅度调制的无线电广播，它是最古老、最简单的调制形式，在 无线电中广泛使用，如调幅广播、无线电话、无线电报、电视图像传输等。
• The technique of AM is by varying the strength of the transmitted carrier wave in relation to the information being sent. For example, changes in the signal strength to reflect the sounds electronically reproduced by a speaker, or to specify the light intensity of television pixels.
字信号，并用可达到CD质量的数字格式进行广播。数字广播有两个标准： Eureka 147 和 WorldDMB。基于MP2音频编解码器的Eureka 147标准是最常用 的。
• The WorldDMB (formerly World DAB Forum) is an international non-governmental organization, which defines the standards for digital audio broadcasting. It represents 120 organizations (mainly broadcasters and manufacturers) from more than 30 countries. On 30 October 2006 the World DAB Forum announced a change in name to WorldDMB (Digital Multimedia Broadcasting) to show that its objectives cover radio, mobile TV and the broadcasting of new media services, but not just the DAB standards.
