“Nothing is simple before you understand it!”
This sentence actually made me think about what “understanding” a problem really is…

very good professor

@donnyab Yes! Indeed. This is a fairly advanced subject which generally isn’t gotten to until one’s senior year of university or more often in a master’s program. If you want to be prepared to understand it all, you’ll need to be able to understand all of those prior subjects. One can always watch the videos and do their best, but if you’re going to put in the work, you may as well put in the work.

I have never understood how digital modulation is actually implemented and why the use of I (In Phase) and Q (Quadrature) components. Hope to understand it with this course….

You should try working your way through Oppenheim/Wilsky’s Signals & Systems and something like John G. Proakis’ Digital Signal Processing as preparation to this course. Berkeley has some good video lectures on the Signals and Systems stuff. Having a good background in Probability Theory will be helpful as well.

I would like to be able to follow this course, but am a bit worried about the prerequisites. Does anyone know of a good course I could take a look at to be ready for this one?

Online Education can become extremely boring. We miss the teachers, the tone of voice, the body language. And also those stories that good teachers share with their students.
But thanks God for these on-line lectures. They are awesome!
