课程名称：BEEE 基础电子与电气工程 课程概述：电子学的实际历史始于1897年J.A.弗莱明发明真空二极管，随后李·德·福雷斯特实现了真空三极管以放大电信号，这一进展促成了四极管和五极管的出现，并在二战前占据主导地位。电气电路与电子电路的主要区别在于，电气电路没有决策（处理）能力，而电子电路则具备这种能力。电气电路仅用于为机器提供电力，而大多数现代电器则是电子电路和电气电路的结合。 电子工程是电气工程的一个分支，关注电磁波谱的应用以及集成电路和晶体管等电子设备的应用。电流、电压、阻抗、电容和电感是电子学与无线电的一些基本元素。除了这些基本元素，还有许多有趣的电子技术元素。在构建电子电路时，你将接触到多个基本电子元件，包括电阻器、电容器、二极管、晶体管、电感器和集成电路。 具体的电子元件包括：微控制器、变压器、电池、保险丝、继电器、开关、电动机和断路器。一个简单的电子系统通常由输入、处理和输出组成，输入变量和输出变量都是信号。系统有多种表示方式，例如数学表示、描述性表示、图示或电路图。 本课程将帮助学习者理解电子学的基础概念及其在现代科技中的应用。
Electronics' actual history began with the invention of vacuum diode by J.A. Fleming, in 1897; and, after that, a vacuum triode was implemented by Lee De Forest to amplify electrical signals. This led to the introduction of tetrode and pentode tubes that dominated the world until World War II. The main difference between electrical and electronic circuits is that electrical circuits have no decision making (processing) capability, whilst electronic circuits do. An electric circuit simply powers machines with electricity..Most modern appliances use a combination of electronic and electrical circuitry. Electronics engineering is a branch of electrical engineering concerned with the uses of the electromagnetic spectrum and with the application of such electronic devices as integrated circuits and transistors. Electrical current, voltage, resistance, capacitance, and inductance are a few of the basic elements of electronics and radio. Apart from current, voltage, resistance, capacitance, and inductance, there are many other interesting elements to electronic technology. When building electronic circuits, you will work with a number of basic electronic components, including resistors, capacitors, diodes, transistors, inductors, and integrated circuits.What are the electronic components?Microcontroller.Transformer.Battery.Fuse.Relays.Switches.Motors.Circuit Breakers.Then we can say that a simple electronic system consists of an input, a process, and an output with the input variable to the system and the output variable from the system both being signals. There are many ways to represent a system, for example: mathematically, descriptively, pictorially, or schematically.
