1. A method for digitizing a band-limited, analog signal, said method comprising:

  • amplifying the analog signal;

    digitizing the amplified analog signal in a preset number of quantizing steps;

    setting a prevailing amplification of the analog signal so that the average value over time of the size of the digitized analog signal is controlled to a predetermined value;

    prestoring all possible values of the digitized analog signal based upon the number of quantizing steps; and

    retrieving a prestored signal corresponding to the digitized analog signal amplified with an inverse amplification of the prevailing amplification.
