The second half addresses the challenge of extracting a "true" signal from data corrupted by noise—a central problem in communications, radar, and control systems.
The mathematical framework for analyzing these systems, using difference equations to represent how the current output depends on present and past inputs (and past outputs for IIR systems).
Practical methods for calculating how filters attenuate or boost specific frequency ranges, including graphical computation methods. Part 2: Optimum Linear Estimation
The book is structured in two halves to guide students and engineers from basic filter design to the practical application of the Kalman filter in noisy environments. Part 1: Digital Filtering Fundamentals
