Second Edition. Kluwer Academic Publishers, 2002
This book is intended as an intermediate-level introduction to the basic theory of analog filters. It covers three major types of analog filters - passive, active, and switched-capacitor. The only knowledge required to follow the material in this book is some basic sophomore-to-junior circuit
theory, electronics, signal analysis, Laplace transforms, and mathematics typically required by most engineering curriculums at the sophomore and junior levels.
