Claim:
A method for generating multiplier coefficients for a (1:m) mixer, comprising the steps of: (a) performing recursive calculation of a multiplier set (MS); (b) selecting a multiplier group (MG) consisting of a number of multipliers from the calculated multiplier set (MS) in dependence on a predetermined signal/noise ratio (SNR NOM ) of the mixer, wherein selecting a multiplier group (MG) comprises (i) selecting a multiplier group (MG) from the multiplier set (MS) consisting of two multipliers (V i , V i +1), the run index i of which produces a signal/noise ratio (SNR)=20 log [(1+√5)/2] 2 ·(i+1/2) that is higher than the predetermined signal/noise ratio (SNR NOM ) of the mixer, or (ii) selecting a multiplier group (MG) from the multiplier set (MS) consisting of three multipliers (Vi, Vi+1, Vi+2), the run index i of which produces a signal/noise ratio (SNR)=20 log [(1+√5)/2]2·(i+1) that is higher than the predetermined signal/noise ratio SNR NOM ) of the mixer; (c) writing the multiplier coefficients (MC) into a memory of the mixer in accordance with the selected multiplier group (MG); and (d) during the step of recursive calculation, after initialization of a first multiplier V 0 of the multiplier set (MS) to zero (V 0 =0) and initialization of a second multiplier V 1 of the multiplier set (MS) to one (V 1 =1), further multipliers of the multiplier set (MS) are calculated in accordance with the following recursion rule: V i+2 =V i +V i+1 for all i= 0, 1, 2 . . . i max , wherein the mixer comprises a 1:10 mixer.
