Abstract
An automatic gain control device capable of reducing signal saturation or signal distortion caused by out-of-band signals of a filter or delay of a control signal. An AGC response control section compares a level of control voltage ('V_I terminal' signal) output from an AGC control section b with a level of control voltage ('V_I terminal' signal) output from an AGC control section c. If the ‘V_I terminal’ signal is below the ‘V_I terminal’ signal, an AGC amplifier is controlled by the ‘V_I terminal’ signal. If the ‘V_I terminal’ signal is above the ‘V_I terminal’ signal, the AGC amplifier is controlled by the ‘V_I terminal’ signal. In the latter case, control information of the AGC control section b is replaced by control information of the AGC control section c so that the AGC control section c controls the AGC amplifier c.
