Lecture 2 | The Fourier Transforms and its Applications

Lecture by Professor Brad Osgood for the Electrical Engineering course, The Fourier Transforms and its Applications (EE 261). Professor Osgood's lecture addresses the question- How can we use such simple functions, sin(t) and cos(t) to model such periodic phenomenon? He takes the students through the first steps in analyzing general periodic phenomenon.

The Fourier transform is a tool for solving physical problems. In this course the emphasis is on relating the theoretical principles to solving practical engineering and science problems.

more than half of those people watching lecture1 quit.

@evanquinnco

look i dont know who writes in arabic or what he says but i know that you must respect other people cultures and languages ....

Everything in this video is the simple (elegant) observation that the exponentials in question form an orthonormal basis of the relevant vector space of integrable functions. There's no rabbit coming out of the hat from that perspective, but it appears these graduates didn't get past elementary calculus.

tough crowd

His discussion of the DC component is so true: I once had a conversation where I was the person looking like the other guy was crazy. The subject was Poisson distributions but the result was the same.

Awesome job!

[TheBobdoctor]

DOKBOB You can't hear the class because his mike does not pick up the noise from them. Look at lecture 1 where he asks for questions from the class but has to switch off his own mike before they can be heard.

[flexchen]

If you look for the matlab program he's talking about, just google for sinesum2 and go for the 1st hit.

[mipsuperk]

Lol, like 13 minutes in he makes a joke, and no one laughs at all.

"If we now a periodic function(an absolut) on an interval (0-1) then we now it everywhere.!."

Well i guess that reason and human mind is not a mathematical thing... should i click the next movie.?.

P.S I think i need to be death in order to real understand mathematics... or just click the next movie. (Excuse my typing)

[hanz12891]

Im feeling soo fucking angry at my prof right now....all he does in class is "muablabblumumbbleblabla" and i cant understand shiT!

while this guy explained everything so well
