The Kindle edition may not be a direct PDF but a reflowable ePub. However, it’s legal, cheap (sometimes ₹450 during sales), and can be read on any device.
If you are a librarian or educator looking to make this book available to more students, contact OUP India for institutional licensing options. If you are a student, ask your faculty to place a copy on course reserve. Let’s build ethical access, not patched PDFs.
The textbook Digital Signal Processing by Tarun Kumar Rawat (published by Oxford University Press) is a comprehensive resource divided into 17 chapters. It covers everything from fundamental discrete-time signals to advanced topics like multirate DSP and spectrum estimation. Table of Contents (Major Chapters)
Based on the official curriculum and publisher details, the book is structured as follows:
Chapter 1: Discrete-time Signals and Systems – Basics of signal types, system classifications, and fundamental operations.
Chapter 2: Sampling and Quantization – Covering A/D conversion, aliasing, and quantization error analysis.
Chapter 3: Convolution and Correlation – Analytical and graphical methods for LTI system response.
Chapter 4: Discrete-time Fourier Series – Frequency domain representation of periodic signals. tarun kumar rawat digital signal processing pdf patched
Chapter 5: Discrete-time Fourier Transform (DTFT) – Analysis of non-periodic discrete signals.
Chapter 6: The z-Transform – Region of convergence (ROC), inverse z-transforms, and system stability.
Chapter 7: Filter Concepts – Introduction to digital filtering, phase delay, and group delay.
Chapter 8: Discrete Fourier Transform (DFT) – Frequency domain sampling and properties.
Chapter 9: Fast Fourier Transform (FFT) – Efficient algorithms like DIT and DIF Radix-2.
Chapter 10: Realization of Digital Filters – Structures including Direct-Form I & II, Cascade, and Parallel realizations.
Chapter 11: Finite Impulse Response (FIR) Filter Design – Windowing techniques and frequency sampling methods. The Kindle edition may not be a direct
Chapter 12: Infinite Impulse Response (IIR) Filter Design – Butterworth and Chebyshev filter approximations.
Advanced Topics (Chapters 13–17): Includes Finite Word Length Effects, Multirate DSP (decimation/interpolation), Optimum Linear Filters (Wiener filters), and Power Spectrum Estimation. Key Features
MATLAB Integration: Contains numerous solved MATLAB programs and end-of-chapter problems to bridge theory with practical simulation.
Extensive Problems: Includes over 600 solved examples, 230 MCQs, and 180 practice problems.
Self-Study Aides: Offers online resources like solutions manuals and additional practice examples through Oxford University Press India. Digital Signal Processing - Tarun Kumar Rawat
OUP India runs occasional textbook donation programs. Contact their academic sales team — they sometimes provide one free PDF per department for social equity cases.

No. A patched PDF implies it has been altered to remove restrictions. This almost always indicates copyright infringement.
Before diving into the PDF controversy, it’s worth understanding the author’s credentials. Tarun Kumar Rawat is a professor in the Electronics and Communication Engineering department at Netaji Subhas Institute of Technology (NSIT), Delhi (now known as NSUT). He holds a Ph.D. from IIT Delhi and has published extensively in signal processing, adaptive filters, and biomedical signal analysis.
His textbook, Digital Signal Processing, is known for:
Because of its practical approach, the book is widely used by undergraduate and graduate students in India and South Asia. The original price (approx. ₹600–₹800 for the paperback) is reasonable by international standards, but for many students, even that is a barrier — hence the search for a "patched" PDF.
The search for “tarun kumar rawat digital signal processing pdf patched” highlights a real problem: students need affordable, easy access to high-quality DSP textbooks. But the solution is not piracy or patched files — it’s promoting open educational resources, library access, and affordable digital editions.
As a student, your integrity matters as much as your knowledge. Using a patched PDF might save ₹700 today, but it adds ethical debt and personal cybersecurity risk. Instead, explore legal options: used copies, library loans, shared purchases, or even emailing the author’s department for aid (many professors will help).
DSP is a beautiful, logic-driven field. Start your journey with clean signals — and a clean conscience.
Some universities subscribe to OUP’s digital library. Log in via your institute’s VPN to access Rawat’s book as a browseable PDF — no patching needed.
