paraffing asked:Hello! Regarding your latest post, you probably know about fourier series? If there aren't many terms in a series, a square wave function can have those small waves along "flat" regions - they flatten out as you add terms, but I think there tends to be a little bit of an overshoot for a while (Gibbs phenomenon). Sorry if I'm just telling you what you already know!
Hi! Thanks a lot for the message, I hope you don’t mind that I’ve shared it, mainly because you’ve expressed what’s going on far better than I can.
