FIELD: information technology.
SUBSTANCE: described is a method and a system for generating a converted output signal from an input signal using a conversion coefficient T. The system includes an analysis window with length La, which extracts an input signal frame, and a unit which analyses transformation of the order M, which transforms discrete values into M complex coefficients. M depends on the conversion coefficient T. The system also includes a nonlinear processing unit, which changes the phase of complex coefficients using the conversion coefficient T, a unit which synthesises transformation of the order M, which transforms the changed coefficients into M changed discrete values, and a synthesis window with length Ls, which generates an output signal va(n) frame.
EFFECT: high reliability of the signal conversion system, and providing improved harmonic conversion with little additional complexity.
