"Linear Systems Analysis" is a textbook for the undergraduate engineering students, covering the basic principles and techniques for modelling, analysis and simulation of linear dynamic systems. The contents are designed to suit the requirements of a first course in this subject. Such a course is a pre-requisite for higher level courses on topics like Control Systems, Network Theory, Communications etc. The subject matter is treated from the point of view of an engineer, that is, the mathematical concepts and results have been correlated and interpreted in terms of behaviour of physical systems. The pedagogical style is oriented towards meeting the learning needs of an average undergraduate student and yet to be challenging enough for the more serious and advanced student.
