Signals and Systems

The book is designed to serve as a textbook for courses offered to undergraduate and graduate students enrolled in Electrical Engineering. The first edition of this book was published in 2014. As there is a demand for the next edition, it is quite natural to take note of the several advances that have occurred in the subject over the past five years. This is the prime motivation for bringing out a revised second edition with a thorough revision of all the chapters. The book presents a clear and comprehensive introduction to signals and systems. For easier comprehension, the course contents of all the chapters are in sequential order. Analysis of continuous-time and discrete-time signals and systems are done separately for easy understanding of the subjects. The chapters contain over seven hundred numerical examples to understand various theoretical concepts. This textbook also includes numerical examples that were appeared in recent examinations and presented in a graded manner. The topics such as the representation of signals, convolution, Fourier Series and Fourier Transform, Laplace transform, Z-transform, and state-space analysis are explained with a large number of numerical examples in the book. The detailed coverage and pedagogical tools make this an ideal textbook for students and researchers enrolled in electrical engineering and related courses.

Dr. Sankaran Palani obtained his B.E. degree in Electrical Engineering in 1966 from the University of Madras, M.Tech. in Control Systems Engineering from Indian Institute of Technology Kharagpur in 1968, and Ph.D. in Control Systems Engineering from the University of Madras in 1982. He has a wide teaching experience of over four decades. He started his teaching career in the year 1968 at the erstwhile Regional Engineering College (now National Institute of Technology), Tiruchirapalli in the department of EEE and occupied various positions. As Professor and Head, he took the initiative to start the Instrumentation and Control Engineering Department. After a meritorious service of over three decades in REC, Tiruchirapalli, he joined Sudharsan Engineering College, Pudukkottai as the founder Principal. He established various departments with massive infrastructure.

He has published more than a hundred research papers in reputed international journals and has won many cash awards. Under his guidance, 17 research scholars were awarded Ph.D. and a large number of scholars are pursuing Ph.D. He has carried out several research projects worth about several lakhs rupees funded by the Government of India and AICTE. As the theme leader of the Indo - UK, REC Project on energy, he has visited many Universities and industries in the United Kingdom. He is the author of the books titled Control Systems Engineering, Signals and Systems, Digital Signal Processing, Linear System Analysis, and Automatic Control Systems. His areas of research include the design of Controllers for Dynamic systems, Digital Signal Processing, and Image Processing. Dr. S. Palani is the reviewer of technical papers of reputed International Journals. He has chaired/organized many International conferences and Workshops
