Ebook: Signals and Systems : Fundamentals

The concepts of signals and systems arise in a wide variety of areas, ranging from
home-oriented consumer electronics and multimedia entertainment products to sophisticated
communications, aeronautics and astronautics, and control. The ideas
and approaches associated with these concepts have great effects on our life in one
way or another. Although the signals and systems which arise across those fields are
naturally different in their physical make-up and application, the principles and tools
for analyzing signals and systems are the same and hence applicable to all of them.
Therefore, an introductory course on signals and systems is fundamental and compulsory
for an engineering under-graduate curriculumin anywell-established tertiary
(education) institutions. Such a course is commonly designed in one of the two forms
below:
– a one-semester subject that intends to provide students with a rich set of concepts
and tools for analyzing deterministic signals and an important class of systems
known as linear time-invariant systems;
– a two-semester subject that expands on the one-semester course by adding more
detailed treatment of signal processing and systems for specified applications
such as communications, multimedia signal processing and control engineering.
This book takes the first form and assumes that the students have a background in
calculus and introductory physics.
