Devices for automatically adjusting an amplifying or attenuating factor

摘要

The invention relates to a device for automatically adjusting an amplifying or attenuating factor (G;ATT) of a plurality of amplifying or attenuating members (1;2;3) connected in cascade, comprising one detector (8;9;10) each for measuring a signal level of a signal present at the input of each amplifying or attenuating member (1;2;3) and one subsequent control unit (14;14'14") each for determining the amplifying or attenuating factor (G;ATT) associated with each amplifying or attenuating member (1;2;3). The control unit (14;14';14") is a forward control unit for determining the amplifying or attenuating factor (G;ATT) associated with each amplifying or attenuating member (1;2;3) as a function solely of the measured signal level of the signal present at the input of each amplifying or attenuating member (1;2;3).
