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 LA eng UL http://joc.kntu.ac.ir/article-1-219-en.html M3 ER -
