1.2.4 Adaptive filters /96 ■ Adaptive filter predict one random process y(n)}from observations of another random process {x(n)}using linear models. The coefficients in adaptive digital filters are updated at each iteration. Adaptive filters usually consist of a general filter block and coefficient update block. 2021年2月 102021年2月 10 1.2.4 Adaptive filters  Adaptive filter predict one random process {y(n)} from observations of another random process {x(n)} using linear models.  The coefficients in adaptive digital filters are updated at each iteration.  Adaptive filters usually consist of a general filter block and coefficient update block
