1. Using 10n F for the capacitor, determine the theoretical output frequency and the peak value of the triangle wave. Record these items in Table 16.7.1.

2. Construct the circuit of Figure 16.5.1 using the 10n F capacitor and the medium speed op amps.

3. Record the output frequency and amplitude of the triangle wave in Table 16.7.1 and determine the deviation between the theoretical and experimental results.

4. Save a copy of the oscilloscope displaying the triangle and square waves as Graph 1.

5. Replace the capacitor with the 1n F unit. Determine the theoretical output frequency and the peak value of the triangle wave using this new value, and record the results in Table 16.7.2.

6. Record the output frequency and amplitude of the triangle wave in Table 16.7.2 and determine the deviation between the theoretical and experimental results.

7. Save the triangle and square wave display as Graph 2. Pay particular attention to the leading and trailing edges of the square wave. Are the wave shapes identical to those created with the first capacitor?

8. Return the 10n F capacitor to the circuit, replacing the 1n F unit.

9. Replace the medium speed op amps with the low speed op amps.

10. Save the triangle and square wave display as Graph 3. Pay particular attention to the leading and trailing edges of the square wave. Are the wave shapes identical to those created with the faster op amps?

11. Estimate and then measure the results for each individual error presented in Table 16.7.3.
