The understanding of signals and systems is a prerequisite to learning digital signal processing and communication systems. This book presents concepts of signals & systems using a large number of well-designed and illustrative solved problems. The book is suitable for a one-semester undergraduate level course in Signals and Systems, for students in Electronics and Communication, Electrical and Electronics and Computer Engineering programs, as well as Information Technology courses. The book is also valuable for post-graduate students and practising engineers for reviewing the basics of signals and systems. It covers topics ranging from introduction to signals and systems, continuous-time (CT) signals and systems, analysis of linear and time-invariant systems, continuous-time Fourier series, continuous-time Fourier transform, sampling, Laplace transform and Z transform. MATLAB codes for all the chapters are given along with a brief introduction.
