Digital: Signal Processing By Sanjay Sharma

The book begins with the fundamentals. It introduces students to the classification of signals (continuous vs. discrete, deterministic vs. random) and systems (linear vs. non-linear, time-variant vs. time-invariant). Sharma’s treatment of Linear Time-Invariant (LTI) systems is particularly noted for its clarity, breaking down convolution sum and difference equations into digestible steps.

If you’re struggling with your DSP course, buy this book—not as your only reference, but as your . Work through every example in Chapters 4 (Z-transform), 6 (DFT/FFT), and 8 (IIR filter design). By the end, the fog will lift. digital signal processing by sanjay sharma

Dr. Sanjay Sharma’s Digital Signal Processing is a widely recognized textbook designed primarily for undergraduate engineering students, particularly those within Indian technical universities. The book serves as a bridge between complex mathematical theories and practical engineering applications, making the dense subject of Digital Signal Processing (DSP) more accessible to beginners.
