Abstract:
In this paper, different cases of the stability of Multiple Adaptive Notch Filter (MANF) are studied. The structure of MANF is composed of N parallel subfilters. Each subfilter estimates the parameters of one the components of quasi periodic signals including the sum of N periodic signals. For this structure, there are three different cases of stability for N=K, N>K and N
