ABSTRACT:
A receiver (100) adjusts its overall gain based on the detected power level of an incoming signal. The receiver is built with two detectors (D1, D2) which operate with different detecting ranges within the dynamic range of the incoming signal. If the actual power level of the incoming signal falls within one of the resolving ranges, an automatic gain control adjusts the gain of the receiver to a corresponding gain value. If not, the resolving range of one of the two detectors is shifted and eventually reduced to cover the portion of the dynamic range in which the power level is comprised. The gain of the receiver is then temporarily adjusted and a new measurement is carried out by the detector using the new resolving range. The AGC then re-adjusts the gain of the receiver based on the measurement given by the modified detector.
