I am trying to solve for the Transfer Function in this Bandpass filter. I have tried several methods. What I am trying to do is use KCL at the three essential nodes at the output of each op-amp. I have most of the equations but the one for the first op-amp(top left) I cant see to figure out what to do. I am working on this project with a few friends and we are struggling with the same spot. Any tips would be great on how to approach this question.
