The amplification means where the joint reception

摘要

PROBLEM TO BE SOLVED: To provide an amplifier repeater for a community receiving system the characteristic of which can efficiently be adjusted.;SOLUTION: Amplifier stages 14, 18 receive outgoing community receiving signals, amplify them and output them. An equalizer 8, an attenuator 10, and a gain control circuit 16 are provided in relation to the amplifier stages 14, 18. Branch signals from each of one-branching units 12, 34 are fed to a level checker, which measures levels. The result of the measurement by the level checker is fed to a control section 50, which controls the equalizer 8, the attenuator 10, and the gain control circuit 16 so that the result of measurement becomes nearly equal to a predetermined value.;COPYRIGHT: (C)2007,JPO&INPIT
