Abstract

본 발명은 더블데크 고속더빙기에서 주파수 변조신호를 복사할 때 발생하는 테이프 상의 드랍 아웃을 보상하는 장치에 관한 것으로서, 재생시 드랍 아웃 구간을 보상하기 위해, 기록시 드랍 아웃 구간을 처리하는 장치를 포함하는 드랍 아웃 보상장치에 있어서, 헤드로부터 출력된 소신호를 증폭하여 출력된 신호 중 드랍 아웃 부분을 보상하기 위해 게이트 펄스를 발생시키는 드랍 아웃 검출회로; 상기 드랍 아웃 검출회로로부터 발생된 게이트 펄스 구간의 신호가 재생될 때, 드랍 아웃 구간을 인식할 수 있도록 드랍 아웃 구간을 뮤트시키는 뮤트회로; 및 상기 뮤트회로로부터 제어되어 드랍 아웃 구간을 제외한 신호만을 증폭하는 리미터회로를 포함한다.The present invention relates to a device for compensating for a dropout on a tape generated when copying a frequency modulated signal in a double-deck high-speed dubbing machine. The present invention relates to a device for processing a dropout section during recording to compensate for a dropout section during playback. A drop out compensation device comprising: a drop out detection circuit for amplifying a small signal output from a head to generate a gate pulse to compensate for a drop out portion of an output signal; A mute circuit for muting the drop out section to recognize the drop out section when a signal of the gate pulse section generated from the drop out detection circuit is reproduced; And a limiter circuit controlled by the mute circuit to amplify only a signal excluding a dropout period.

따라서, 상술한 바와 같이 본 발명에 따른 드랍 아웃 보상장치는 기록시 러미터회로를 뮤트하여 드랍 아웃 구간을 증폭하지 않으므로써, 재생시 드랍 아웃 구간을 정상적으로 복원할 수 있어 노이즈가 발생하지 않는 효과를 갖는다.Therefore, as described above, the drop-out compensator according to the present invention does not amplify the drop-out section by muting the limiter circuit during recording, so that the drop-out section can be restored normally during playback, so that noise is not generated. Have
