3) After building the adder circuit (Fig. (7)) using just two Vin, V0 = -5.00 V, V1= 5.00 V, and the resistors R0 = Rf = 1 kOhms, and R1 = 2 kOhms, the circuit out voltage was calculated using the following relationship,
- \(V_{out}=-\left(\frac{R_f}{R_{in}}\left(V_1\right)\ +\ \frac{R_f}{R_{in}}\left(V_2\right)\right)=-7.5\ V\)
and the voltage measured came to,
- \(V_{out\ measured}=\ -7.465\ V\)
verifying that the circuit is working properly.
