This book was written for an experimental freshman course at the University of Colorado. The course is now an elective that the majority of our electrical and computer engineering students take in the second semester of their freshman year, just before their first circuits course. Our department decided to offer this course for several reasons:

  1. we wanted to pique student' interest in engineering by acquainting them with engineering teachers early in their university careers and by providingwith exposure to the types of problems that electrical and computer engineers are asked to solve;
  2. we wanted students entering the electrical and computer engineering programs to be prepared in complex analysis, phasors, and linearalgebra, topics that are of fundamental importance in our discipline;
  3. we wanted students to have an introduction to a software application tool, such as MATLAB, to complete their preparation for practicaland efficient computing in their subsequent courses and in their professional careers;
  4. we wanted students to make early contact with advanced topics like vector graphics, filtering, and binary coding so that they would gain amore rounded picture of modern electrical and computer engineering.

In order to introduce this course, we had to sacrifice a second semester of Pascal programming. We concluded that the sacrifice was worth making because we found that most of our students were prepared for high-level language computing after just one semester of programming.

We believe engineering educators elsewhere are reaching similar conclusions about their own students and curriculums. We hope this book helps create a much needed dialogue about curriculum revision and that it leads tothe development of similar introductory courses that encourage students to enter and practice our craft.

Students electing to take this course have completed one semester of calculus, computer programming, chemistry, and humanities. Concurrently with this course, students take physics and a second semester of calculus, as well asa second semester in the humanities. By omitting the advanced topics marked by asterisks, we are able to cover Complex Numbers through Linear Algebra , plus two of the three remaining chapters. The book is organized so that the instructor can selectany two of the three. If every chapter of this book is covered, including the advanced topics, then enough material exists for a two-semester course.

The first three chapters of this book provide a fairly complete coverage of complex numbers, the functions e x and e j θ , and phasors. Our department philosophy is that these topics must be understood if a student is to succeedin electrical and computer engineering. These three chapters may also be used as a supplement to a circuits course. A measured pace of presentation,taking between sixteen and eighteen lectures, is sufficient to cover all but the advanced sections in Complex Numbers through Phasors .

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
