ABSTRACT:
A gain of an amplifier of a receiver is automatically controlled based on a level of a signal received by the receiver. The instantaneous value of the envelope of the received signal is detected sequentially at predetermined time intervals. The first interval average value providing an average of the instantaneous value for a first predetermined time length, and the second interval average value providing an average of the instantaneous value for a second predetermined time length are determined. The difference between the instantaneous value and the first interval average value is determined. When the difference exceeds a predetermined threshold value, the gain of the amplifier corresponding to the second interval average value is set after a predetermined third time length.
