Grading

• Midterm 1 25
• Midterm 2 25
• Final 35
• Quiz 10
• HW 5

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 dont, until you do
  it yourself)
• Some quiz questions from HW (same or similar)

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. -gt light)Audio
amplifiers (info elect.-gt 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 gt mostly theory of info
processing Electronics, circuits, digital design,
power, electromechanics, sensors, etc. gt
Physical representation and manipulation of info
and energy
Sometimes information dominates completely (e.g.
Information 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.

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) gt
  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.
