These videos are a world away from one’s student days, listening to the monotone drawl of a disinterested lecturer as his lesson limped its way toward the finishing post. These videos are a world away ...

Mathematical transforms can be a great help in understanding signals. Imaging trying to look at a complex waveform and figuring out the frequency components without the Fourier transform. [Artem ...

If you ask most people to explain the Fourier series they will tell you how you can decompose any particular wave into a sum of sine waves. We’ve used that explanation before ourselves, and it is not ...

Fourier series, from the heat equation to sines to cycles.
