# 3.6: Procedure


1. Calculate the voltages at points A, B, and C, and record them in Table 3.7.1.

2. Assemble the circuit of Figure 3.5.1.

3. Using the input combinations listed in Table 3.7.2, apply the appropriate signals to $$V_1$$ and $$V_2$$. Measure the output signal using the oscilloscope, and record the values in Table 3.7.2.

4. Connect $$V_1$$ to a 10 volt peak-to-peak 1 kHz sine wave. Make sure the oscilloscope inputs are set to DC Coupling, and then connect probe 1 to $$V_1$$, probe 2 to $$V_2$$ and probe 3 to $$V_{out}$$.

5. Connect $$V_2$$ to point A. Measure the output voltage and save a copy of the oscilloscope display as Graph 1.

6. Connect $$V_2$$ to point B. Measure the output voltage and save a copy of the oscilloscope display as Graph 2.

7. Connect $$V_2$$ to point C. Measure the output voltage and save a copy of the oscilloscope display as Graph 3.

## 3.6.1: Computer Simulation

8. Build the circuit of Figure 3.5.1 in a simulator and run a Transient Analysis echoing steps 4 through 7. Compare the results to the waveforms generated experimentally.
