The Fast Track to Determining Transfer Functions of Linear Circuits is a condensed student guide teaching readers about first-, second- and third-order linear transfer functions commonly encountered in the design of electronic systems. Fast Analytical Circuits Techniques (FACTs) reduce mathematical overhead and often eliminate the use of complex equations for circuit analysis. If a circuit is too complicated, it is split into simpler subcircuits that can be evaluated individually. The intermediate results are then assembled to form a desired final result. FACTs work on RLC networks, but also on active circuits featuring operational amplifiers (op-amps) or transistors. Chapters List: Transfer Functions Fast Analytical Circuits Techniques Zeroes of a Transfer Function Generalized Transfer Functions. First-Order Transfer Functions Second-Order Transfer Functions Third-Order Transfer Functions Appendix: Illustrating the Process of Determining Poles and Zeroes The goal of this book is to be practical and lead the reader to solve problems by applying step-by-step approaches. In many cases, the only required accessories are a sheet of paper and a pen. Chapters one to four are a crash course on the FACTs. The following chapters detail how to determine transfer functions of classical networks from the first to third order. After going through the proposed examples at your own pace, the reader will master the techniques for analyzing RLC networks in the frequency domain. The book is an ideal companion for students who want to understand and master linear circuit behavior. BSEE, MSEE and Ph.D students will find many useful descriptions and methods which can be applied to linear circuit design and further study.
