Signal processing is the field that is concerned with the analysis,
modification and synthesis of signals that represent information about
the behavior or characteristics of some phenomenon. It is a subfield of
information engineering, electrical engineering, and mathematics. Signal
processing techniques serve to improve signal transmission fidelity,
subjective quality, storage efficiency, and detect or emphasize signal
characteristics that are of particular interest. Signal processing can
be of different kinds based on its application, such as analog signal
processing, discrete-time signal processing, continuous-time signal
processing, digital signal processing, etc. Such techniques are useful
in image and video processing, wireless communication, process control
and audio signal processing, besides several other important
applications. Different approaches, evaluations, methodologies and
advanced studies on signal processing have been included in this book.
There has been rapid progress in this field and its applications are
finding their way across multiple industries. With state-of-the-art
inputs by acclaimed experts of this field, this book targets students
and professionals.
