Everything about Adaptive filter

System with self-optimizing transfer function

An adaptive filter is a system with a linear filter that has a transfer function controlled by variable parameters and a means to adjust those parameters according to an optimization algorithm. Because of the complexity of the optimization algorithms, almost all adaptive filters are digital filters. Adaptive filters are required for some applications because some parameters of the desired processing operation are not known in advance or are changing. The closed-loop adaptive filter uses feedback in the form of an error signal to refine its transfer function. Wikipedia →
