PPT-Basic feedback theory and Oscillators

by DVKamat Faculty Department of EampC Engg MIT Types of feedback There are two types of feedback in amplifiers Positive feedbackregenerative feedback Negative feedbackdegenerative feedback. 1 Oscillation results from an unstable state ie the feed back system cant find a stable state because its transfer function cant be satisfied Equation 1 becomes unstable when 1A 0 because A0 is an undefined state Thus the key to designing an oscil Circuits.

Your music exam will be next lesson. It will be a listening exam, where you are played music and asked questions about them. It will cover all the topics you have done this year, plus some general music questions. . Alfredo D. Bobadilla. An element of the electrical circuit experiences movement or oscillations..
