As circuit complexity continues to increase, the microelectronic industry must possess the ability to quickly adapt to the market changes and new technology through automation and simulations. The purpose of this book is to provide in a single volume a comprehensive reference work covering the broad spectrum of filter design from passive, active, to digital. The book is written and developed for the practicing electrical engineers and computer scientists in industry, government, and academia. The goal is to provide the most up-to-date information in the field.

Over the years, the fundamentals of the field have evolved to include a wide range of topics and a broad range of practice. To encompass such a wide range of knowledge, this book focuses on the key concepts, models, and equations that enable the design engineer to analyze, design, and predict the behavior of large-scale systems that employ various types of filters. While design formulas and tables are listed, emphasis is placed on the key concepts and theories underlying the processes.

This book stresses fundamental theory behind professional applications and uses several examples to reinforce this point. Extensive development of theory and details of proofs have been omitted. The reader is assumed to have a certain degree of sophistication and experience. However, brief reviews of theories, principles, and mathematics of some subject areas are given. These reviews have been done concisely with perception. The compilation of this book would not have been possible without the dedication and efforts of Professor Rashid Ansari and Dr. A. Enis Cetin, and most of all the contributing authors. I wish to thank them all.
