Signals and Systems is a comprehensive textbook designed for undergraduate students of engineering for a course on signals and systems. Each topic is explained lucidly by introducing the concepts first through abstract mathematical reasoning and illustrations, and then through solved examples.

The book provides a simultaneous coverage of continuous-time and discrete-time signals and systems. Beginning with classifying signals, the book sequentially covers important topics such as convolution and correlation of signals, continuous-time Fourier series, discrete-time Fourier series, continuous-time Fourier transform, sampling. Hilbert transform, Laplace transform, and z-transform. A chapter on MATLAB programs presenting the applicability of the software to problems of signals and systems has also been included at the end of the book

Signals and Systems is a textbook designed for undergraduate students of engineering for a course by the same title. This textbook uses a student-friendly approach to explain the fundamental concepts of the subject. It includes numerous solved examples with step-by-step solutions for easier understanding of the theoretical concepts.

Beginning with classifying signals, the book moves on to other topics such as convolution and correlation of signals, CTFS, DTFS, CTFT, Sampling, Laplace Transform, and z-Transform. One complete chapter is devoted to MATLAB programs and another chapter is entirely devoted to Hilbert Transform.

The subject matter is presented by illustrating the concepts first through abstract mathematical reasoning and then through solved examples. Solving the number of multiple choice questions and numerical exercises at the end of the chapters will help students to apply the concepts learnt in the chapters.
