Patent ID: 7218269

Claim:
A method for enlarging an interference-free dynamic range of non-linear signal-processing components in receiver systems, in the conversion of input frequencies f in into output frequencies f out , comprising: calculating at least one linear combination of at least one input frequency f in,t , f in,b and a fixed, predetermined oscillator f LOn of the components from an output signal of the component, for at least one output frequency f out,s , f out1,s , f outs,2 ; comparing said combination with any desired output frequency f out,t of the component; recognizing an output frequency f out,s , f out1,s , f outs,2 as a spur; and eliminating said output frequency recognized as a spur from the output signal of the component, if the calculated linear combination corresponds to any desired output frequency f out,t of the component, within a predetermined frequency and power range.
