# 18.6: Procedure


1. Derive the equation for $$V_{out}$$ for the circuit of Figure 18.5.1. Calculate the lowest usable (“integratable”) frequency, $$f_{low}$$. Record these items in Table 18.7.1.

2. Calculate the integrator’s output voltage for the following inputs and record them in Table 18.7.2:

• 1 volt peak sine wave at 2 times $$f_{low}$$
• 1 volt peak sine wave at 10 times $$f_{low}$$
• 1 volt peak square wave at 2 times $$f_{low}$$
• 1 volt peak square wave at 10 times $$f_{low}$$

1. Assemble the integrator circuit.

2. Save the display of the output of the integrator for each of the inputs listed in step 2, above. Call these Graphs 1 through 4, respectively. It is very important to note the phase of the output waveform with respect to the input waveform.

3. Apply a 1 volt peak sine wave one decade below $$f_{low}$$. Save the output signal as Graph 5. Does the circuit appear to be integrating?

4. Apply a 1 volt peak square wave one decade below $$f_{low}$$. Save the output signal as Graph 6. Does the circuit appear to be integrating?
