"The text is designed for the undergraduate student of Electronics and Communication Engineering as the first introduction to Signals, their behaviour and representations, and System responses. The content has been carefully sequenced to help students make a smooth transition to the understanding of Signals by introducing the previously learnt concepts of Laplace and Z Transforms (in mathematics) early in the discussions in this text. With numerous pedagogical features and MATLAB examples, the book will aid the student in understanding the practicality of the subject better."
