Signal processing Signals and systems. The tools and methods for making signals useful. Spinning Numbers Fourier series Questions Julia, 06 April 2021 Hi Willy, I watched all of your Khan Academy videos. Super helpful. Thanks so much! Will you be making more videos on more advanced topics like Bode plots and transfer functions? ↪︎ Reply to Julia Willy McAllister, 06 April 2021 Julia - I released this page a little earlier than expected. Signals is my next effort on Spinning Numbers. I’ll start out in the time domain first, describing properties of sine waves and combinations of sines in picture form. It’s a good thing to have in your head. That will be followed by the transition to frequency domain, where Bode Plots and filter theory is developed.
