# The algebraic relationship between the output and input voltage is to be determined for the given circuit. Concept introduction: Based on the given circuit, we have two inverting summing amplifier configuration. Generally, the output of an inverting summing amplifier for two inputs is given by v 0 = − R f ( v 1 R 1 + v 2 R 2 ) , R f represents feedback resistance and R 1 and R 2 represent the resistance at the input terminals corresponding to the respective input voltages v 1 and v 2 .
