The general feedback theorem: a final solution for feedback systems

Design-oriented analysis is a paradigm based on the recognition that design is the reverse of analysis, because the answer to the analysis is the start big point for design. Conventional loop or node analysis leads to a result in the form of a "high entropy expression," which is a ratio of sums of products of the circuit elements. There are many methods of D-OA, some of them little more than shortcuts or tricks. In this paper, the spotlight is on a new approach to analysis and design of feedback systems, based on the general feedback theorem (GFT) is discussed.
