Sundararajan D. Digital Signal Processing. An Introduction 2ed 2024

Textbook in PDF format

This textbook for a one semester introductory course in digital signal processing for senior undergraduate and first year graduate students in electrical and computer engineering departments is concise, highly readable, and yet provides comprehensive coverage of the topic. Each new topic is presented with examples and figures. The highly mathematical content of the topic is presented lucidly to make the learning the subject easier. Practical aspects of the subject are clearly indicated so that the student can apply the principles in real applications. MatLAB programs for FIR and IIR filter design are provided as supplementary material online.
The prerequisite is a course in signal and systems or equivalent and some experience in programming. The features of this book are the detailed coverage of finite impulse response optimal filter design with MatLAB programs (available online), clear and concise presentation of the difficult concepts using DFT of short length data or appropriate figures, physical explanation of concepts, large numbers of figures and examples, and clear, concise and, yet, comprehensive presentation of the topics.
