To see subtitles in other languages: Click on the gear symbol under the video, then click on "subtitles." Then select the language (You may need to scroll up and down to see all the languages available). --To change subtitle appearance: Scroll to the top of the language selection window and click "options." In the options window you can, for example, choose a different font color and background color, and set the "background opacity" to 100% to help make the subtitles more readable. --To turn the subtitles "on" or "off" altogether: Click the "CC" button under the video. --If you believe that the translation in the subtitles can be improved, please send me an email.

+Anders Feder, Patreon has the ability to accept payments through PayPal. As for donating per video, I wasn't sure whether to accept donations per video or per month, as both are options I could have selected in Patreon, but I decided on doing it per month as I thought that this would be less confusing to people. I am not sure I understand the last part of your sentence, but if you find that you can't create a Patreon account, please let me know.

I think this comment sums up why in 5, 10, 20 years, as the quality of free and inexpensive online education continues to improve, traditional brick-and-mortar education will lose its value significantly. If you can learn everything you would from obtaining a degree online at a fraction of the cost of attending a university, and more importantly can prove to employers that you know your stuff, how much will that degree be worth? From the employer's perspective it shouldn't matter as long as you can demonstrate your ability. Obviously there are exceptions (Doctors, for example), but AI, robotics and 3D printing could make short work of human doctors in our lifetimes - maybe we'll just train people with great bedside manners to supervise.

I'm on my fourth year of Electrical Engineering, and the frequency spectrum has always been an abstract concept that I could never truly wrap my head around. Explaining it as a density of frequencies that, when inputed to sine functions, form a given function was a huge a-ha moment for me, thank you so much!

Great analogy...yes, it's the difference between understanding the notation of something and understanding the thing itself at a deep level... I sometimes think the language of mathSSS obscures more than it reveals :D eg imagine trying to describe the colour red to a blind person. You can use the most complex language in the world but it wouldn't work. I think there needs to be some way of describing motion of things separate from language and maths, maybe. What that is I don't know, but it would be pretty handy!

Beautiful. Really enjoyed it. I hope this will help young students want to pursue a deeper understanding of signal processing. The more general form of this idea introduces imaginary numbers (i.e., complex math) creating a very powerful tool. The Fourier transform is just one, among other types of transform, that allow us to manipulate the way we see mathematical functions. Just like logarithms allows us to do multiplication by adding and then transforming back to get the desired product, Fourier transforms allow us to study the characteristics of signals in time by looking at the signal in the frequency domain.

That's the beauty of the visual approach .... you SEE the transform emerge by the simple shifts of perspective. The transform emerges from recognizing that a combination of sin waves of various frequency , amplitude and phase can be summed to emerge over sample time a particular output wave form ...this is exactly what the transform does...the video doesn't actually provide the equation but one should be able to see how the terms of it emerge from simple visual examination of this video...which is what makes it so awesome. If I'd had this video as a guide when I was learning the FT back in the mid 90's as an undergrad it would have cemented the mental imagery I was creating to try and understand it myself.

FYI,, fourier representation of any signal is a way in which signal can be represented as sum of orthogonal signals(complex exponential signals which is a sine wave by a simple formula) ....

FINALLY! a unique video that's as brilliant as it is simple, and as educating as it is inspiring, has been found in the KZbin sea of Fourier Transform videos. I've been struggling to understand how frequency circles relate to a real-time waveform in a Fourier context until I watched this video. It made such a seemingly complex geometrical bundle of mess look as easy as 1+1=2. Thank you for clarifying the confusion that acted as a roadblock to a deep understanding of Fourier Transforms. ABSOLUTELY SPECTACULAR !! It's so inspiring because it shows the immense and unimaginable intelligence and power of the creator behind his creation of nature.

Staggering graphics that perfectly demonstrate what is so hard to get across verbally. Been a maths student for 50 years yet I learned something today that was staring me in the face all that time but I never spotted it before - the sine wave formation on the 'z' axis. Also a great way to demonstrate why mathematicians use radians and not degrees in complex situations. Astounding video..... many thanks.

The sphere and line model REALLY makes it make more sense to me than the typical circles connected at midpoints that you see in videos. It lets me see that its essentially adding a vector instead of just being random. I could have comd to thst intuition eventually but this helped a lot.
