Hello
I would very much like to understand how the following is derived if anyone has an idea. A full derivation would be great but some method pointers and/or references would be equally appreciated. I have chosen the simplest circuit from the datasheet (the LP filter) in the hope that if I can understand this I can move onto the more complex ones. I understand how the LM13700 works in terms of its internal circuit but things like this leave me confused as ive only worked with discrete (and simpler) circuits in the past
the official formula is here also
Thanks to anyone who knows how to approach this
