4 Adaptive Filters Applications

Adaptive filters have become invaluable system component in modern industry. Without adaptive filters, many of the systems we currently rely on in our daily life would not exist. This section summarizes the most common applications of adaptive filters currently used in commercial systems. System identification and forward modeling applications using adaptive filters are described in Section 2.4.1, equalization and inverse modeling in Section 2.4.2, adaptive linear prediction in Section 2.4.3, adaptive autoregressive spectrum analysis in Section 2.4.4, echo cancellation in Section 2.4.5, and finally adaptive interference canceling in Section 2.4.6
