| Zusammenfassung: | A method for separating spectrums of an input signal having a first spectrum and a second spectrum by mixing the input signal at a first mixer with a first frequency to obtain a first mixed signal; mixing the input signal at a second mixer with second frequency to obtain a second mixed signal; displacing the first mixed signal and/or the second mixed signal up and down by the difference of the first and second frequency obtaining at least one lower auxiliary signal and at least one upper auxiliary signal, respectively; and extracting the first spectrum and/or the second spectrum using the lower auxiliary signal and/or the upper auxiliary signal as well as the first mixed signal and/or the second mixed signal. Further, measurement devices for separating spectrums are shown. |
