- Referring to Fig. 9.4, all the three input resistor values are equal and each is equal to the value of feedback resistor. Therefore, the gain of the summing amplifier is 1. As a result, the output voltage is the algebraic sum of three input voltages.

therefore, Vout = – (V1 + V2 + V3) = – (3 + 1 + 8) = – 12 V
