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 L, 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 L, which generates an output signal v(n) frame.EFFECT: high reliability of the signal conversion system, and providing improved harmonic conversion with little additional complexity.37 cl, 12 dwg |
