This book provides a comprehensive treatment of DSP techniques commencing from an
elementary level of sampling process. It covers topics like Z-transforms, filter approximations,
digital filters (both IIR & FIR), Discrete Fourier Transforms (DFTs), Fast Fourier Transforms
(FFTs), filter realisation techniques, Multi-rate Signal Processing, DSP Processors, and DSP
At the end, MATLAB programming is given on various DSP topics.
The aim is to impart adequate knowledge to the undergraduate-level students in DSP area.
This book focusses on theoretical concepts and problem-solving.
