Use the idea of Exercise D2.8 on page 73 to design a summing Op amp with output Vo = 2v₁ +5V₂ - V3 Simulate the circuit with 741 Op Amp and bias voltage of ± 15 V. Include the following results: 1. Tabulate the values of the resistors. 2. Labelled Schematic of the circuit from the simulation software. 3. For (i) v₁ = 1, V₂ = 3, V3 = 4 and (ii) v₁ = 5, V₂ = 2, V3 = 12 Tabulate expected and simulated output vo Note: Op Amp output must not exceed the bias voltage otherwise the Op Amp will saturate and behave nonlinearly.
