1. The problem statement, all variables and given/known data For this problem, the diagram of the circuit is attached. It was assigned to find the frequency response function of the circuit. 2. Relevant equations E_o/E_i= -Zf/Zi 3. The attempt at a solution I know for the top branch of the circuit, it has a negative feedback loop so therefore its: E_o/E_i = -Rf/Rin The problem I am having is with the resistor connected to the non inverting input. Since it doesn't have a loop structure, I question what it's output is and how to account for that in my frequency response function. The only examples I have found are of differential amplifiers. However those have two resistors that end up being connected to ground. Any assistance is appreciated.
