A ferromagnetic layered composite ABAB... ABA with nonuniform: distribution of anisotropy parameter is studied. The effects of damping leading to non-zero line-width of ferromagnetic resonance peaks are also taken into account. As a result the dependence of spin wave parameter B and resonance line-width on parameters characterizing system under consideration were obtained for the case of uniform anisotropy parameter and for quadratic distribution of this parameter in magnetic layers, respectively.
