1. Electrical Engineering Six Primary Specialties 1. Computers / Computer Engineering 2. Electronics 3. Communications 2 nd Largest of all Engineering disciplines About 35% of all engineers are electrical 4. Power 5. Controls 6. Instrumentation

2. Computers / Computer Engineering Primarily concerned with hardware: microcode that controls processors, design of processors, design of computers. Many University departments combine Electrical Engineering with Computer Science or Computer Engineering Computer Engineering: Most rapidly growing discipline in all of engineering

3. Computer Science: Primarily concerned with software Computer Languages include BASIC (Beginner’s All-purpose Symbolic Instruction Code) COBOL (Common Business Oriented Language) UNIX FORTRAN (Formula Translator) Linux (named for Linus Torvalds) C++Java DOS (Disk Operating System) C# (C sharp) Computer Science Programming Languages Operating Systems Windows

4. Design of Circuits and Electric devices, used to… Microelectronics: Electronics at microscopic level Produce, amplify, detect, rectify electrical signals Transistors: invented 1947 Electronics Semiconductors: not quite a conductor, not quite an insulator Integrated Circuits (ICs): Co-invented by Intel and Texas Instruments Silicon Valley’s growth based on growth of microelectronics industry

5. Broad range of areas Consumer Electronics Satellite Imagery Military Applications Lasers Cell Phones Communications Fiber Optics Wireless Communication (Radio Frequency, or RF) Infrared technology (night vision goggles)

6. Electrical Engineers involved in… Power Generation Power Transmission Power Distribution Nuclear Power Power Alternative power sources: Solar, Wind, Fuel Cells Hydroelectric Projects (including Dams) Generating electricity from steam (Geysers, CA)

7. Systems which control automated operations Control systems used to compare a measured quantity to a desired standard and make adjustments Examples include… Anti-lock braking systems in automobiles Auto-pilots features in jumbo jets Controls ‘Driving’ unmanned BART trains New joystick design for video games

8. Using electronic devices (such as Transducers) to measure physical parameters, including temperature, pressure, flow rate, speed, acceleration, voltage, current. Often responsible in processing, storing, and transmitted collected data. Often closely associated with Controls engineers Instrumentation Examples: Cable TV box Many automotive applications Weather stations

9. Institute of Electrical and Electronic Engineers (IEEE) Through its members, the IEEE is a leading authority in technical areas ranging from computer engineering, biomedical technology and telecommunications, to electric power, aerospace engineering and consumer electronics, among others. Professional Society: IEEE
