Digital Signal Processing

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 realization techniques, Multirate Signal Processing, DSP Processors, DSP applications. 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 focuses on theoretical concepts and problem solving.
