# 19.6: Procedure


1. Derive the equation for $$V_{out}$$ for the circuit of Figure 19.5.1. Calculate the highest usable (“differentiable”) frequency, $$f_{high}$$. Record these items in Table 19.7.1.

2. Calculate the differentiator’s output voltage for the following inputs and record them in Table 19.7.2:

• 1 volt peak sine wave at one-half$$f_{high}$$
• 1 volt peak sine wave at one-tenth$$f_{high}$$
• 1 volt peak triangle wave at one-half$$f_{high}$$
• 1 volt peak triangle wave at one-tenth$$f_{high}$$

1. Assemble the differentiator circuit.

2. Save the display of the output of the differentiator for each of the inputs listed in step 2. 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 above$$f_{high}$$. Save the output signal as Graph 5. Does the circuit appear to be differentiating?

4. Apply a 1 volt peak triangle wave one decade above $$f_{high}$$. Save the output signal as Graph 6. Does the circuit appear to be differentiating?
