Thank you Sir,the way you express your opinion and the way of teaching are just amazing.Now there is some light in the tunnel that i will probably manage to take the Advance Digital Signal Processing Exam.

Hey, just wanted to say that because of your videos I feel MUCH more comfortable with diff eq. You make this subject much easier to understand!

The tears that are flowing from my eyes right now are tears of joy. I cant believe I finally understood the backbone of the Unit Step Function, now I can finally have some fun with these. Thank you Khan Academy!!

You are my hero sir. I watched your videos last year in my ode and pde class, and thought I'd never need this stuff again. This is the second time you've made me actually understand laplace.

@norwayte its similar to the Jacobian in multivariable calculus, technically its a transformation from a nth dimensional vector space to another nth dimensional vector space. where the scaling factor keeps the integrands the same size. in other words the first vector space has the same area of the second vector space if and only if its divided by the scaling factor of the second vector space.

The size of writing, the colors you use and the somehow "low" definition make this and some other videos pretty hard to watch. My eyes got tired. Apart from that - excellent.
Please, explain (again) what these transforms (Laplace, Fourier, Lorentz...) really are. What is the idea behind it?
(We "transform" to another "world", hope the best and reverse-transform to use the result?)
Time-domain... frequency domain - worlds - what?!

The quality is only bad the first few minutes after the video is uploaded (while it is being processed). Re-watch it again in a few minutes.
