CHARACTERISTICS OF BROKEN-LINE APPROXIMATION AND ITS USE IN DISTORTION AUDIO EFFECTS
Jiří Schimmel, Jiří Mišurec · 2007
This paper deals with an analytic solution of spectrum changes in scalar non-linear discrete systems without memory, whose transfer characteristics can be approximated via broken-line function. The paper also deals with relations between the 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 characteristics that are approximated via broken-line function. These characteristics are judged from the dissonance point of view. ( x[ n] − xPi) for xi ≤ x[ n xi y =
