Best for understanding the "how"—how to solve the equations, how to design the filter, and how to pass the exam with high marks. Final Verdict
Detailed methodologies for both FIR (Finite Impulse Response) and IIR (Infinite Impulse Response) filters, which are the bread and butter of DSP. Hardware Realization: digital signal processing by nagoor kani
Kani avoids heavy mathematical overkill in the first read. He explains terms like aliasing, linear convolution, and circular convolution in plain English before the equations. Best for understanding the "how"—how to solve the
