    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?
