Step of 6 2.010E Refer to Figure E2.9 in the By using superposition theorem, the total response by the input is equal to sum individual response by each input. Determine the response only due to Set the voltages =0 and V3 0 Re-draw the modified circuit diagram. vx + + 3 kΩ - Figure 1 Step 6 Apply current law at node (positive end). 2k 3k Apply current law at node (negative end). 1k 9k (1k) Substitute 3 for in the 5 (1) Step 6 Determine the response only due to Set the voltages = 0 and =0 Re-draw the modified circuit diagram. + + - Figure 2 Step of 6 Apply current law at node (positive end). 3k 2k Apply Kirchhoff's current law at node (negative end) 1k 9k (1k) Substitute 2 5 for in the equation. 4v2 (2) Step of 6 Determine the response only due to Set the voltages =0 and =0 Re-draw the modified circuit diagram. V3O + + Figure 3 Step of 6 For the inverting amplifier, write the expression for R, (9k) = (3) Determine the expression for Use equations (1), (2) and (3). Therefore, the expression for output voltage
