Abstract: A method for enlarging the interference-free dynamic range of non-linear signal-processing components in receiver systems, in the conversion of input frequencies fin into output frequencies fout. According to the invention, at least one linear combination of at least one input frequency fin,t, fin,b and a fixed, predetermined oscillator fLOn of the components is calculated from the output signal of the component, for at least one output frequency fout,s, fout1,s, fouts,2, which combination is compared with any desired output frequency fout,t of the component, whereby the output frequency fout,s, fout1,s, fouts,2 is then recognized as a spur and eliminated from the output signal of the component, if the calculated linear combination corresponds to any desired output frequency fout,t of the component, within a frequency and power range that can be predetermined.
