A method for increasing the spurious-free dynamic range of non-linear signal processing components

摘要

A method for increasing the spurious-free dynamic range of non-linear signal processing components in receiver systems in the reaction of input frequencies f_in in the output frequencies f_out, characterised in that, for at least one output frequency f_{out, s}, f_{out1, s}, f_{out2, s} from the output signal of the component is at least a linear combination of at least one input frequency f.sub.i_{in, t}, f_{in, b} and a fixed predetermined oscillator frequencies f_Lon the components is calculated, the linear combination with a desired output frequency f_{out, 1} the component is compared, wherein the output frequency f_{out, s}, f_{out1, s}, f_{out2, s} then, as a track and recognized from the output signal of the component is eliminated when the calculated linear combination within a predetermined frequency - and power range ld a desired output frequency f_{out, t} the component corresponds to.
