Now we're almost done. 
I wanted to talk about how the course is 
going to end a little bit and talk about 
the final. 
So, there's one last problem set to work 
problem set 12 that we have to do. 
And there is a final examination for 
those who want to get a, obtain a 
certificate for the course. 
But before we talk about the final I want 
to point out, we have covered a lot of 
ground. 
We started with circuits, learning about 
all RC circuits. 
We have continued that, to talk about 
digital and anolog signals and we have 
seen some applications of these ideas in 
communication systems. 
And learn some very new, and then 
exciting things in information theory, 
about how to compress signals and about 
how to communicate signals from one place 
to another with no error. 
This material will prepare you for fair 
number of other courses that are on 
Coursera. 
the scolder range from, hardware oriented 
kind of courses. 
There's a course in Robotics. 
And there are these Signal Processing 
courses, like fundamentals of electrocal 
engineering has prepared you to take. 
I'm sure if you look at Ed Ex you'll see 
some more. 
And as time goes on, more and more 
courses will rely on this course, to 
prepare you for them. 
Now let's talk about the final. 
The final does cover the entire course. 
it goes all the way from circuits to 
information theory. 
It has exactly the same format as a 
problem set. 
You wont find any surprises since you've 
been working the problem sets the answer 
kind of formats are the same and 
questions asked are very similar. 
Now to prepare for the final, you have 
two weeks starting on the 15th of April, 
to prepare for the final and to work it. 
You will have three attempts to work the 
final when we get there. 
but I do want to point out some things 
that are in the link to this video. 
You may have noticed all these document 
icons. 
What those are, are the problem sets and 
the exercises with solutions, that you 
can download and look at to help you 
prepare for the final. 
I recommend that you write down key 
formulas, things like the Fourier 
transform tables, Fourier transform 
properties, things like that. 
Anything that you think is especially 
important and put them down in one place. 
So that you won't have to be looking up 
these kind of things while you take the 
final. 
And this also helps you, learn the 
material, of course. 
Now, taking the final you have two 
consecutive days, 48 hours, to work the 
final anytime during that two-week 
period. 
So take the first part of the two-week 
period for example to prepare for the 
final, and then when you think you're 
ready, you start the final itself, you 
have two days to complete it. 
The final is entirely open book. 
Anything that has to do with this course, 
you can access while you are taking the 
final during that 48 hour period. 
They're all available to you. 
You can look at anything that's, that's 
there. 
The final should be your work. 
No collaboration with anybody else, and 
let me know how you, have gotten the 
material down. 
The discussion forum will be limited to 
issues with the questions. 
You can also ask the other students 
about, I don't understand this, do you 
have a, a way of thinking about it, that 
kind of thing is fine. 
on the, on the discussion forum. 
But no answers to problems will, will, 
should be put on the forum. 
And, to obtain a certificate for the 
course, all, everything depends on a 
passing grade on the final. 
Those on signature track will have a 
little bit different certificate than the 
ones who don't, aren't on signature 
track. 
But if you pass the final, you will earn 
a certificate. 
Well there's one last thing I'd like to 
talk about, and that's the survey. 
Please complete the survey. 
I want to hear what you think about this 
course and how we can improve it in the 
future. 
You'll also find a question or two there 
about a Lab course that we're envisioning 
that would go along with this course. 
And so anyway I've had a great time 
teaching this course online, and I hope 
you've enjoyed taking it.
