This book deals with the fundamental concepts of digital signal processing. We have attempted to explain the basic principles and concepts in a simple and lucid way so that students can understand the fundamentals with clarity. We have explained various concepts by giving lot of examples. We would advise the students to have a strong back- ground of signals and systems as the prerequisite for a thorough understanding of the fundamentals of Digital Signal Processing. KEY FEATURES: - • Most of the topics are written in simple English and many examples are worked out for the benefit of the students. • Each chapter begins with a brief introduction and ends with practice problems. • Theoretical concepts are well explained. • Accurate and detailed derivations are provided in this book. • Design procedures for digital filters are illustrated with clarity. • Two sets of model question papers are provided for students' reference. • DSP lab programs using MATLAB, DSP Processor (TMS320C6748) and Simulink are also included.
