Network Synthesis and Filter Design: Network Functions, Synthesis of One and Two Port Networks, Filter Design

The book is written for an undergraduate course on the Network Synthesis and Filter Design. It provides comprehensive explanation of theory and practice of techniques of network synthesis and passive and active filter design. The book starts with explaining the various types of network functions, all pass functions, minimum phase functions, delay functions and ladder network. The chapter on fundamentals of network synthesis includes Hurwitz polynomial, properties of positive real functions and Sturm's theorem. The book covers the various aspects of one port network synthesis explaining the network synthesis of LC, RC, RL and RLC networks using Foster and Cauer forms. The book also includes the synthesis of transfer functions. The chapter on passive filter design includes the discussion of various filter approximations, magnitude and frequency normalization and frequency transformation. It continues to explain the active filter design and active filter synthesis. It incorporates the discussion of negative impedance converter, gyrator and frequency dependent negative resistance. Finally, the book discusses the sensitivity function, factors affecting gain sensitivity and effects of op-amp parameters on the performance of active filters. Each chapter starts with the background of the topic. Then it gives the conceptual knowledge about the topic dividing it in various sections and subsections. Each chapter provides the detailed explanation of the topic, practical examples and variety of solved problems. The explanations are given using very simple and lucid language. All the chapters are arranged in a specific sequence which helps to build the understanding of the subject in a logical fashion. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
