Title: Gain control circuit and receiving system

Abstract: Disclosed herein is a gain control circuit including: an amplifying section configured to amplify an input voltage in such a manner that amplitude of an output voltage at an output terminal is kept constant; an allowable voltage acquirer configured to acquire an allowable voltage of an apparatus connected to the output terminal; a voltage divider configured to divide the output voltage according to a ratio between a maximum voltage of the amplified input voltage and the allowable voltage; and an adjusting section configured to further amplify the amplified input voltage according to the ratio and supply a resulting voltage to the output terminal.
