This book is an introduction to electric network theory. The first half of the book is devoted to network analysis and the remainder to network synthesis and design. What ARE network analysis and synthesis? In a generally accepted definition of network analysis and synthesis, there are three key the EXCITATION, the NETWORK, and the RESPONSE. Network analysis is concerned with determining the response, given the excitation and the network. In network synthesis, the problem is to design the network given the excitation and the desired response.
