Abstract
An automatic gain control circuit including a variable gain amplifier () adapted to receive a received signal (R) and to output an amplified signal (A) to an analog to digital converter (), and a gain controller () which is connected to said variable gain amplifier () for receiving said amplified signal (A) and for controlling a gain of said variable gain amplifier (). The gain controller () is adapted to determine an occurrence of a threshold event each time the amplified signal (A) has reached a predetermined threshold, decrease the gain of the variable gain amplifier () at each occurrence of a threshold event, measure a delay since the last threshold event, increase the gain of the variable gain amplifier () if the delay is greater than a delay specified value and if the gain of the variable gain amplifier () is not maximum.
