Goals:

Electrical engineering is the practice of electronic circuits, with today's technologies allowing routine and low cost of incredibly complex integrated circuits consisting of 10's of millions of simple devices created within a thin silicon crystal about th size of an index finger's fingernail. The devices provide a means of establishing relationships between the flow of charge (electrical currents) and the force fields (electrical voltages). The course will provide a background in the understanding of these underlying electronic devices and sets of interconnected devices. The simplest devices are resistors, capacitors, and inductors, establishing a relatively simple relationship between their currents and voltages. More complex devices include transistors whose current-voltage characteristics are controlled by a separate control voltage or current. Other electronic devices establish connections between the physical world and the electronic world (with "sensors" sensing physical effects such as temperature, distance, and pressure and "actuators'' changing the physical environment). Electronic circuits include "analog" circuits whose operations concern currents and voltages varying continuously in time and amplitude and "digital" circuits whose operation is based on binary states and numbers. The course will provide background in simple analog and digital circuits.

Policies and Procedures

• Class attendance is expected. From time to time, class attendance will be taken and recorded. 10 points of extra credit will be given to each student who regularly attends class according to these attendance checks.
• Homework will be assigned on an approximately weekly basis. Discussion of homework problems among students is expected but each student must submit his/her own solution to the problems. Homework solutions are expected to be submitted in a neat and complete form, with all major steps in obtaining the solution shown explicitly if partial credit is to be received. Obvious examples of copying will be severely penalized.
• The final grade will be computed as follows: Each homework, exam, quiz , and project report will be weighted equally. The student's lowest grade will be dropped, not including the final exam
• Students are expected to read and understand the textbook reading assignments, including example problem solutions. Lectures should be regarded as supplementary material, rather than review of the textbook material.
