1. The problem statement, all variables and given/known data I want to find the overall transfer function of Instrumentation amplifier with a DC-Suppression filter. I know how to calculate the TF of a normal Instrumentation amplifier. But when feedback is given from the Filter to the IA, I couldn't find it. 2. Relevant equations I used Superposition theorem and found the voltage V01 and V02 for the circuit given in attachment 1. I have posted the equations for voltage V01 and V02 in attachment 2. The final equation which I need to find is in attachment 3. 3. The attempt at a solution I got the equations for voltages V01 and V02 as given in attachment 2. Please help me out to find the TF of the circuit. Thanks!!
