Analog & Digital Signal Processing 2e
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.
Why Read This Book
You should read this book if you want a single, accessible text that treats analog and digital signal processing as complementary topics and connects theory to implementation issues. You will gain practical insight into transforms, filter design (analog and digital), FFT algorithms, and finite‑word‑length effects that matter when moving from math to real DSP hardware.
Who Will Benefit
Undergraduate and early‑graduate students, plus practicing engineers who need a compact, practical bridge between analog signal‑processing concepts and digital DSP implementation.
Level: Intermediate — Prerequisites: Basic calculus, complex numbers and algebra, introductory signals & systems (LTI systems, impulse response, convolution); basic circuit concepts helpful but not mandatory.

How It Compares
Covers much of the same undergraduate territory as Proakis & Manolakis but is more balanced between analog and digital topics and generally more accessible; Oppenheim & Willsky is more rigorous on signals/systems theory, while Baher emphasizes practical connections and implementation.
