This book provides an introduction to transmission line effects in the time domain. Fundamentals including time of flight, impedance discontinuities, proper termination schemes, nonlinear and reactive loads, and crosstalk are considered. Required prerequisite knowledge is limited to conventional circuit theory.  The material is tutorial for electrical and computer engineers on the topic of transient signals on transmission lines. Emphasis has been placed on aspects of the subject that have application to signal integrity and high-speed digital circuit design issues, including proper termination schemes to avoid impedance discontinuities, reactive and nonlinear loads, and an introduction to crosstalk. The coverage focuses on the very important topic of transmission line transients which have been de-emphasized in most current textbooks.  This book is prepared to supplement traditional texts for advanced students studying electromagnetics and for a vast array of practicing electrical engineers, computer engineers and material scientists with interests in signal integrity and high-speed digital design. In this second edition, examples and new problems have been added throughout.  A new chapter on differential transmission lines has also been incorporated
