Method and apparatus for automatic gain control in a digital receiver and receiver equipped therewith

摘要

The method relates to the automatic gain control of a digital radio receiver comprising a chain of amplification of the intermediate frequency (2).. 11 coupled to a digital / analog converter - (12). It consists of measuring (17, 19) the high frequency energy and of the signal applied by the chain of amplification of the intermediate frequency in the digital / analog converter - (12) to measure the energy at low frequency of the output signal of the receiver and to control the gain of the chain of amplification of the intermediate frequency from the energies high frequency and low frequency of the signal. & br / application: digital radio receiver.
