The importance of signal analysis (frequency analysis of signals) in modern theory of linear systems and communication theory cannot be overstressed. The study of signals leads into the analysis of linear systems and frequency transform methods on one hand on the other hand it leads directly into communication theory. This book presents a unified treatment of the analysis of linear systems (frequency domain analysis of lumped and distributed system) and basic communication principles (modulation de modulation correlation noise information transmission). There are certain significant differences in the approach in this book from that generally used in other texts. The point of view here tends to be more physical than axiomatic. This textbook is primarily written for advanced undergraduates who have had an elementary course in circuits or system analysis. An understanding of the book requires only a modest background in calculus and elementary circuits. Hence it can be an effective text for self study by practicing engineers who are interested in the analysis of linear systems and communication theory. 608 pp. …
