The book is designed for:

The book is closely mapped to undergraduate DSP syllabi. Topics appear in the order most exams expect: : Comprehensive coverage of Z-Transforms

Discussions on how these mathematical models are actually implemented in digital processors. Practical Utility Discrete Fourier Transform (DFT)

Introduction to continuous and discrete-time signals, sampling theorem, and quantization.

If you are looking for philosophical depth, buy Oppenheim. If you are looking for a practical, result-driven, and student-friendly companion to survive—and even enjoy—Digital Signal Processing, It remains, arguably, the most effective exam-focused DSP textbook ever written for the Indian subcontinent.
