Questions

Answer the following questions in your lab report.

1. Verify that the gain of the circuit shown in Figure is , using the same general procedure as outlined in Section . You may assume the op-amp is ideal.
2. We have seen some examples of clipping in an operational amplifier circuit. Explain how and why clipping should be accounted for in designing an amplifier circuit. More specifically, discuss the possible effects of clipping due to poor design in a high-fidelity audio amp.
3. Explain why turned on when it did in Section . Can you think of some practical uses for a comparator?
