Excellent! Normally I do not pay attention much to too much theory, but this one is made simple and not simpler! I dislike mathematics and I avoid it like the plague as I think I suffer from mild dyscalculia. This, however, I find very doable. Incidentally, how do I actually choose resistors? I mean, resistors for any circuits. It is because I understood that big resistor has more noise than small one, always use the smallest resistor merely for a component to function, no more and no less. Problem is, nearly no body explains how to actually do it. There is only one TH-camr (The AudioPhool) I found does it. Sadly, he explains only for transistor. I need to know for operational amplifier as well because a chip has far less noise compared to discrete devices, and a single chip simplifies life many times more than discrete devices.
thanks simple to understand very helpfull

so basically K = (-Rf/Ri)(higher cutoff/(high cutoff + low cutoff))?
