Use your text and class notes to study. The particularly important parts of the text are: Ch 12 Feedback and Stability Section 12.1. 12.2.1. 12.2.3. 12.4. 12.4.1. 12.9 in your textbook and all class notes. Here are some questions that should be answered. There are possibly many others in the text, so review class notes, your text and work the Exercise problems in the textbook. 1a. Define negative feedback. 1b. Define positive feedback. 2. Describe the effect of negative feedback on the gain and bandwidth of a feedback amplifier 3a. What are the potential" disadvantages of negative feedback? 3b. What are some advantages of negative feedback? 4. Define loop gain. Be very specific and define any symbols used carefully (if used). How is loop gain related to system stability? How is loop gain used to define stability? In class we used Bode Plots to examine stability.
