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)

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 CarriesEnergy Information Analog signals Sensor readings, analog communicatins, TV signals, control signals, button press (doorbell) Digital signals Digital communication, computer networks, microcontrollers,... Heater, vacuum cleaner, motors,... TV, LCD displays (info + elect. -> light) Audio amplifiers (info + elect.-> sound) 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. 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

9. Our emphasis Circuits basics Signals and systems Electronics Digital design Want you to learn basics of these subjects  Simple but powerful ideas, 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.
