Patent ID: 7092877

Claim:
A method for suppressing noise interference with the following steps: gaining of an analytical signal from an input signal (S in ); calculation of an instant amplitude signal (IA) from the analytical signal; calculation of an instant phase signal (IFI) from the analytical signal; non-linear modification of the instant amplitude signal (IA) into a modified instant amplitude signal (IA mod ); linkage of the modified instant amplitude signal (IA mod ) with the instant phase signal (IFI) into an output signal (S out ), wherein the non-linear modification of the instant amplitude signal (IA) is carried out as a result of an evaluation of the input signal (S in ), and wherein the evaluation is performed as a result of an evaluation function which is calculated from the instant amplitude signal (IA) and an instant frequency signal (IFR) gained from the temporal derivative of the instant phase signal (IFI) in order to obtain an evaluation index (n).
