Abstract
In an automatic gain control circuit which has a variable gain amplifier 30 for amplifying an input TDM reception signal 160 in accordance with a controllable gain, an analog-to-digital converter 40 for converting an amplified TDM reception signal 170 into a digital signal 180, and control section 50 for determining an optimized value of the controllable gain in response to the digital signal 180 so as to supply the variable gain amplifier 30 with the optimized value of the controllable gain, the optimized value of the controllable gain is determined by the use of a signal of the time slot S(-1) immediately before the predetermined time slot S(0) when receiving the input TDM reception signal 160.
