ABSTRACT:
A mixer for mixing a signal, present as a sequence of time-discrete values with a time interval between two time-discrete values defining a first sampling frequency from a current frequency to a target frequency, includes a first mixer implemented to convert the signal from the current frequency to an intermediate frequency to obtain an intermediate frequency signal based on the first sampling frequency, wherein a spectral interval between the intermediate frequency and the current frequency depends on the first sampling frequency. Further, the mixer includes means for converting the intermediate frequency signal into a converted intermediate frequency signal which is based on a second sampling frequency. Additionally, the mixer includes a second mixer which is implemented to convert the converted intermediate frequency signal from the intermediate frequency to the target frequency to obtain a target frequency signal which is based on the sampling frequency.
