i know very good the signal processing but i didnt know what is the difference between it and the digital signal processing
so please if one know any book that can satisfy my needs pleazse reply me
bye

Re: hii all

try to find this book in a library or so:
Analog & Digital Signal Processing, Second Edition
Hussein Baher
ISBN: 0-471-62354-7
Paperback
520 pages
July 2001

discription:
Building on the success of the first edition, this popular text book has now been updated and revised. Covering both analog and digital signal processing techniques in an evenly balanced manner, Professor Baher provides an excellent introductory and comprehensive text emphasising how analog and digital techniques complement each other rather than compete.
Brings the entire area of signal processing within the scope of modern undergraduate curricula
Discusses topics such as spectral analysis of continuous and discrete signals (deterministic and random),

Fourier, Laplace, and z-transforms, analysis of continuous and discrete systems and circuits, design of analog and digital filters, fast Fourier transform algorithms and finite word-length effects in digital processors
Presents a final chapter on advanced signal processing (including linear estimation, adaptive filters, over-sampling sigma-delta converters, and wavelets) to encourage further interest
Contains numerous solved examples throughout and MATLAB(r) exercises at the end of each chapter

Written primarily for undergraduates, Analog Digital Signal Processing will also be an authoritative text for postgraduate students and professional engineers.

Preface.
General Introduction.

The Fourier Series in Spectral Analysis and Function Approximation.

The Fourier Transformation and Generalized Signals.

The Laplace Transformation and Some of its Applications.

Analog Signal Processing Systems.

Digitization of Analog Signals.

Discrete Signals and Systems.

Design of Digital Filters.

The Fast Fourier Transform and Its Applications.

Stochastic Signals and Power Spectra.

Finite Word-length Effects in Digital Signal Processors.

hii all

signal processing is related to every operation on signals (nalog and digital and also discrete)
but digital signal processing is about operations on digital signals(or analog signals which convert to digital)

Re: hii all

To be precise Digital Signal Processing is nothing but writing a computer program.

i.e., you write a program to modify a given sequence of numbers to anoither

sequence of numbers. This process of modification is called Digital Signal

Processing.
