1. What happens to the accuracy of differentiation as the input frequency is decreased?
2. At very high frequencies, does the differentiator behave more like a true differentiator, or like an amplifier?
3. What are the advantages of using a medium speed FET-input op amp such as a 351 over a slower bipolar device such as a 741?
4. What is the purpose of the 100 \(\Omega\) resistor?
5. What is the purpose of the 1.5 nF capacitor?
