This paper deals with an analytic solution of spectrum changes that appear in nonlinear discrete systems without memory whose transfer characteristics can be approximated via piecewise linear function. The paper also deals with relations between the mutual harmonics ratio and the approximation parameters. Furthermore, the dependence of the harmonics ratio on the amplitude of a harmonic input signal is presented for the most common systems whose transfer characteristics are approximated via piecewise linear function.
