  1. EEE393 Basic Electrical Engineering Kadir A. Peker kpeker@bilkent.edu.tr Tel: x5406

  2. Book: • Circuits, Devices and SystemsRalph J. Smith5th edition • Will follow loosely • Home page: • www.bilkent.edu.tr/~kpeker(Schedule, syllabus etc) • STARS

  3. Grading • Midterm 1 25% • Midterm 2 25% • Final 35% • Quiz 10% • HW 5%

  4. HOMEWORK 5% • Once every 1-2 week • Will drop 2 worst of homework grades • %20 off each late day (starting after class, same day) • May grade only some problems in the HW (without telling beforehand) • Do not copy from others (but you can discuss) • Want you to: 1-review during the week (open the book at least once)2-Learn the mechanics of problem solving (you may think you know when you see it in the class; but you don’t, until you do it yourself) • Some quiz questions from HW (same or similar)

  5. Schedule Office Hour Other times: E-mail preferred. Can call. Can drop by and see if I am busy or not.

  6. What is electrical engineering • ...areas ranging from wireless communications to biomedical diagnostics... • Fuel-efficient power generation, electronic speech recognition, self-assembling molecular electronics ... • Advanced Energy Technologies, Speech-Based and Haptic Human-Computer Interfaces, Distributed and "Smart" Sensor Design, Streaming and Broadcast Multimedia, Electromagnetics and Remote Sensing, Systems-on-a-chip Design and Testing, Intelligent Transportation Systems, Signal Processing and Compression, Mechatronics and Genome Automation, Advanced Wireless Networks and Communications, Microelectromechanical Systems, and Nanotechnology • Ovelap with CS, bioelectronics... • Nowadays, more code and algoriths then devices

  7. Core Areas • Computer Hardware, Computer Software, Controls, Communications and Signal Processing, Electronics, Fields and Waves • Signals and systems, electronics, digital systems

  8. Electricity is a means for information Electricity Carries Energy Heater, vacuum cleaner, motors, ... TV, LCD displays (info + elect. -> light)Audio amplifiers (info + elect.-> sound) Information Analog signals Sensor readings, analog communicatins, TV signals, control signals, button press (doorbell) Digital signals Digital communication, computer networks, microcontrollers, ... Signals, systems, communication, control, computer software, etc => mostly theory of info processing Electronics, circuits, digital design, power, electromechanics, sensors, etc. => Physical representation and manipulation of info and energy Sometimes information dominates completely (e.g. İnformation theory started from electrical communications, but now is almost a completely mathematical field)Signal and image processing (e.g. Mpeg and mp3) mostly all about algorithms.

  9. Our emphasis • Circuits basics • Signals and systems • Electronics • Digital design • Want you to learn basics of these subjects • Simple but powerfulideas, concepts, analytical tools

  10. Basic Ideas: Circuits Basics • Circuit elements • Resistor, capacitor, inductor, voltage and current sources, etc. • Element equations. • Device modeling. • Solving a circuit • Kirchoff, reduction, equivalent circuits, superposition,... • Review of circuits from physics, + some more • Start AC circuits (capacitors and inductors) => Transition to dynamic systems

  11. Basic Ideas: Signals and Systems • Linearity. Linear time invarient systems. • Time domain and the transform domain (Fourier: signals, spectrum, bandwidth. Laplace: systems, stability, feedback) • There are different ways to view the same data • The impulse response • These are very fundamental concepts in EE (and in many other engineering fields)

  12. Basic Ideas: Electronics • Semiconductor basics • Diodes and transistors • What is all the fuss about “the transistor”? • What does it do? • Where is it used? • How is it used? • Meet the Op-Amp • Cool things you can build using an op-amp

  13. Basic Ideas: Digital Design • Know the toolset • Gates (AND,NAND,OR,NOT,...) • Flip-flops, counters, registers, memory, ... • Microcontrollers,... • State-machines. Digital system design.
