  • Patent number: 5043999
    Abstract: Circuit arrangement for digitally setting the gain factor of a digitally adjustable receive amplifier. For digitally setting the gain factor of a digitally adjustable receive amplifier independently of the reception signal, the circuit arrangement for positive and negative reception signals amplified by the gain factor has comparators whose outputs are fed back via respective feedback switching network to a comparison input of the respective appertaining comparator. As a result of the feedback switching networks the signal level at each of the comparison inputs has different comparison values which are dependent on the signal levels at the output of the respective comparator. Whenever the signal level of the reception signal exceeds one of the comparison values, a counter, that may be a non-linear counter, is decremented by one step and thereby provides a counter reading indicating the gain.
