Adaptive filter

An adaptive filter is a processing tool that automatically adjusts itself to changing conditions in real-time. Think of it as a smart filter that learns from the input signals it receives, modifying its settings to improve performance. For example, in noise-canceling headphones, the adaptive filter minimizes background noise by continuously adapting to new sounds, providing clearer audio. It’s widely used in communication systems, signal processing, and echo reduction, enabling systems to respond dynamically and optimally to unpredictable environments without needing manual adjustments.
