The book is written for an undergraduate course on the Communication Network and Transmission Lines. It provides comprehensive explanation of four terminal symmetrical and asymmetrical networks, attenuators, filters, network synthesis, equalizers, transmission line theory and Smith chart.

The book starts with explaining the symmetrical and asymmetrical four terminal networks which form the basis of attenuators and filters. Then book provides the detailed discussion of various types of attenuators and filters. The discussion of composite filters, lattice filter and crystal filter is also included in support. The book incorporates the discussion of Hurwitz polynomials and positive real function and continues to explain the network synthesis of LC, RC, RL and RLC networks. The book also explains the various types of equalizers.

The book covers the transmission line parameters in detail along with reflection on a line, reflection loss and reflection factor. The chapter on transmission line at radio frequency includes parameters of line at high frequency, standing waves, standing wave ratio, single stub matching, double stub matching and Smith chart.

The book uses plain, simple and lucid language to explain each topic. The book provides the logical method of explaining the various complicated topics and stepwise methods to make the understanding easy. The variety of solved examples is the feature of this book. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
