The book is devoted to a detailed study of feedback theory as applied to linear electronic circuits. It has been written with two particular objectives in mind. The first is to develop a generalised feedback theory which does not rely on the separation of a feedback circuit into an amplifier and feedback network component, and yet it is capable of accounting for all the effects associated with feedback. The need for such a theory is more necessary than ever before owing to the more complex manner in which a transistor behaves compared with a thermionic valve. The second objective is to provide a broad view of the important problem of stability and its relation to the closed-loop transient response, open-loop frequency response and driving-point imped...
