摘要:
A method (300) for determining inter-modulation distortions products of a mixing stage includes: driving (301) a signal input of the mixing stage based on an input signal, wherein an amplitude of the input signal is switched between a first level and a second level, and wherein a frequency of switching the amplitude is smaller than a frequency of the input signal; detecting (302) at a signal output of the mixing stage a first output signal responsive to the driving of the signal input with the input signal, wherein the amplitude of the input signal is switched to the first level, and a second output signal responsive to the driving of the signal input with the input signal, wherein the amplitude of the input signal is switched to the second level; and determining (303) the inter-modulation distortions based on the first output signal and the second output signal.
