Now we have to add Vout1 to Vout2 to complete the third step of the Superposition Theorem. After factorizing the gain component 1+R4/R3, the summing amplifier transfer function becomes the mathematical relation shown in (7). (7) Q.E.D. >>> <<< This formula shows that this sum is a...
Let’s write down what we know: If Vin1 = 0V then Vout1 = 4V and If Vin2 = 5V then Vout2 = 5V, where by Vin1 and Vin2 I noted the input range limits, and by Vout1 and Vout2 I noted the output range limits. Let’s choose one of the summing amplifier inputs to be Vin,...
What about a summing amplifier with 4 inputs or with 5? Better, let’s derive the summing amplifier transfer function forninputs (Figure 4). That way, one can use this formula in a simulation program or a math program like Mathcad to determine the output level for a certain pattern ...
