Final verdict:
If DSP exams make you sweat, Nagoor Kani is your lifeline, not your Bible. Use it for problems and clarity, but don’t stop here if you want to truly master digital signal processing. digital signal processing by nagoor kani

Who Should Buy This Book? (Target Audience Segmentation)

  1. The B.Tech ECE Student (Semester 4/5): Absolutely essential. Do not enter the exam hall without it. It is often the official textbook.
  2. The Self-Learning Hobbyist (with Basic Math): If you know calculus and complex numbers but find Oppenheim too dense, start with Kani. Learn the mechanics of DSP first.
  3. GATE/ESE Aspirants: Use this book for Practice (especially the numerical sections on Z-transform and FFT), but use standard references for Theory because GATE has moved toward conceptual understanding.
  4. The Lecturer: If you are a professor setting question papers, the unsolved exercise section is a great source for "a, b, c" type variations on standard problems.
