Abstract:

Adaptive digital filters are being used and proposed for various applications. The adaptive recursive filter by Feintuch is an example. A stability triangle is developed analytically for this nonlinear adaptive recursive filter using a frozen-time viewpoint. There are reasons to believe that the average stability triangle is correlated to the true stability region for all modes of operation. Computer simulation of two cases of the adaptive filter in the coefficient evaluation mode shows that the stability triangle predicts the stable region with reasonable accuracy for the cases considered.
