Hello.
I'm Dr Ferri.
Welcome to the course on linear circuits.
This course will be taught by
two different people, myself and Nathan
Parrish.
I'm a professor and associate chair for,
for the school of
electrical engineering at Georgia Tech,
and Nathan is a graduate student.
An overview
of the course is, well, it's on linear
circuits,
which is the analysis of
circuits including resistors,
capacitors,and inductors.
We're looking at two different sources,
one is direct
current sources and the other is
alternating current sources.
And we'll be looking at the time domain
and in the frequency domain.
The target audience are people with a
scientific or
technical background, who are not
necessarily electrical or computer
engineers.
This course is taught in conjunction with
a class
that we have at Georgia Tech that is for
non-majors.
That is, students that are in, that are at
engineering, but not in electrical
engineering as their primary major.
Because our course in electrical
engineering goes into a
little bit more depth than the course for
non-majors.
So this course would be great for someone
who wants to
do review or an overview, but not quite as
in depth
as a major in electrical or computer
engineering would do.
Background preparation.
We expect that you have had a first course
in
calculus, so that you understand how to do
derivatives and integrals.
That you're familiar with matrices and
linear
algebra, and you're comfortable with
working with vectors.
That you've had a background in complex
numbers, and can work with complex
numbers, and
that you've had some sort introduction to
circuit elements
at the level that you, with CNA physics
class.
The learning outcomes.
By the time that this course ends, you
should be able to deter-, to
determine voltages and currents in the
resistive
network, with single or multiple DC
sources.
Be able to sketch the transient response
of RC
and RLC circuits to step changes in the
source voltage.
Be able to determine steady-state
responses to sinusoidal
inputs, and this is often called AC
analysis.
Be able to analyze the frequency of
response of filters,
and finally be able to analyze the power
of reactive circuits.
This course is divided up into five
modules.
Each module builds upon itself, and here
is shown
a concept map of how the different modules
relate
to one another.
The background module just gives you some,
you know, a short
background information that, which you
might get from a physics class.
It's just a review.
And then we start with the more difficult,
or the main topics starting with resistive
circuits.
Well with resistive circuits, we have to
draw some background from the background
module.
And then the third module is reactive
circuits, where we add capacitors and
inductors to our circuits and then we
build upon some
of the analysis methods that we learned
with resistive circuits.
And in addition, the frequency analysis
module
leads up to the interesting topic of
filters.
And we have to build upon our previous
modules for that.
As we start each of these modules we will
show the
concept map, we will show the specific
topics within each module, and
then we will also show what we bring
forward from the previous modules.
And the reason we do the concept map is we
want to get
the big picture of this course and how
things relate, to each other.
Here are some hints in how to succeed in
linear circuits.
First and foremost, be active, take notes.
Pretend you're in a regular class, and
you're taking notes.
You either take notes completely by hand,
or you print out the slides and
make notes right on the slides.
Now, the slides that we provide to you are
only
a help for you, in taking notes, so all of
the material we cover in the class,
especially our handwritten
comments on our slides, will not be on
those printed slides.
It's up to you to, to add in additional
comments on those printed slides.
So to help you out, we will provide slides
and cells, as well as a document of
handouts
of slides for each module.
So there's a PDF of all the slides.
for given module.
Next, what we like for you to do when you
take
these notes is to try to identify and
organize your notes.
And organize important concepts and
skills.
The last lesson for each module is called
the
wrap up, and it's basically a study guide
that says.
You should be able to do certain things.
You should be able to solve problems a
certain way.
You should know certain facts and it lists
these out.
So make sure you study those before you do
each quiz for each module.
Next, people learn by testing their
knowledge.
When they test their knowledge and they
find that they don't know
something, then that's the time for them
to go back and review.
We're helping to trigger this by
giving short quizzes in each lesson.
So every lesson, every video lesson, has a
quiz in
there, multiple quiz questions, that are
very basic, very conceptual ideas.
And if you don't get those cracked then
you've
missed something.0 Go back and review the
video again.
We also intermittently provide a pause
button in our lecture.
And that pause button
is to tell you really to pause the lesson,
to pause
your video, and to try answer the question
that was just asked.
And this is to mimic what a professor does
inside a classroom, when a
professor says, what do you think will
happen if I do such and such?
Or what is the answer to this problem?
And the class has time to stop and think
about it.
So we want you to do same, the same
things.
Stop and think whenever we provide this
pause button.
You should do the homework online.
Do the quiz after every module.
And that, again, these are ways of testing
your
knowledge, to make sure that you do
understand it.
Another thing is to ask and answer
questions in the forum.
not only asking the questions of other
people, we would like for students
to have a, to be working together, have a
community of online learners.
So we want you ask questions, and also try
to answer other people's questions.
You'll find that you understand things a
lot better if
you're able to answer and explain things
to other people.
People also learn by making associations
with prior knowledge.
We're trying to help this along by
providing the concept
matter, and in each module, we'll be
telling
you, these are the concepts that you
learned
earlier in this class, and this is how
we're going to be using them in this
module.
So making associations with prior
knowledge, and
understanding the big picture of this
course, will
help you to understand the facts and,
and problem solving skills that we're
teaching you.
Also, relate this material to practical
problems that
you've learned outside of this class, you
know,
things that you've learned in your work
experience or other personal experience.
And to help you with this, we have a lot
of lab demos, which show practical use of
this material.
As lab demos are an inherent part of this
class, so
there will be homework problems on there,
and quiz problems as well.
So we want you to learn them for their own
sake, but
also to help you identify this, and make
associations of the theoretical
knowledge that we're giving you with some
real practical knowledge.
So the policies for the class.
No direct email to the instructional
staff.
Rather, we want you to send all questions
and comments to the forum.
And the forum will be monitored.
We want only respectful and constructive
comments and questions.
In addition, going to, go to the forum
to ask questions, but also to answer
questions.
You'll find that you'll be able to
understand things better yourself if you
try to explain it to other people.
Now this course is being taught in
conjunction with the Georgia Tech course,
a regular course that we have for credit
for our own students here.
And those students have a required text
book, and
they have required labs that are
associated with this class.
So as a courtesy to the online community,
we'll be providing some of the references.
For example, I'll provide
a, a reference to this, the textbook,
which is purely optional for you.
And also, I will print the labs, I'll post
the
labs that we have required for our on
campus students.
It's not required for you to do the labs,
but I would encourage you, if you're
curious, to
buy the data acquisition board and do the
labs
on your own, may help you understand the
material.
And so I welcome you to this course on
linear circuits, and
I'll see you in the video lectures online
and also on the forum.
