摘要
The present invention relates to a broadband automatic gain control apparatus for a European stereo, and more particularly, to a broadband automatic gain control apparatus for a European stereo, which comprises an FM sound trap unit 10 for preventing interference of an FM sound carrier, (Not shown) for removing high frequency noise and color carrier components among the output signals of the FM sound trap unit 10 between the nichrome signal processing unit 40 and the FM sound trap unit 10 and the amplification unit 30, The filter unit 20 is provided to feed back the automatic gain voltage of the nibbler signal processing unit 40 to the amplifying unit 30 to control the gain of the amplifying unit 30 to eliminate the influence of the FM carrier It is possible to prevent the deterioration of the digital carrier caused by deviating from the normal deviation of the FM carrier, and since it can be applied to a wide band, It is possible to listen to a sound without a good quality.
