Abstract
디지탈 비데오테이프 레코더의 픽업장치를 통하여 발생된 재생신호로부터 디지탈데이타를 재생하는 데이타재생장치가 개시된다.A data reproducing apparatus for reproducing digital data from a reproducing signal generated through a pickup device of a digital video tape recorder is disclosed.
본 발명에 따른 데이타재생장치는 변조신호를 입력하는 미분기; 미분기에서 발생된 미분된 재생신호를 입력하는 반전/비반전증폭기; 반전/비반전증폭기에서 발생된 반전증폭된 신호와 비반전증폭된 신호를 입력하는 비교기; 비교기의 비교출력을 입력하는 래치; 및 변조신호를 입력하고, 그의 피크구간에서 래치를 활성화하는 게이트 신호를 발생하는 게이트펄스 발생부를 포함함을 특징으로 한다.A data reproducing apparatus according to the present invention comprises: a differentiator for inputting a modulated signal; An inverting / non-inverting amplifier for inputting a differential reproduction signal generated in the differentiator; A comparator for inputting an inverted and non-inverted signal generated by the inverted / non-inverted amplifier; A latch for inputting a comparison output of the comparator; And a gate pulse generator for inputting a modulation signal and generating a gate signal for activating the latch in its peak section.
본 발명에 따른 데이타재생장치는 미분된 재생신호를 반전/비반전증폭하고, 반전증폭된 신호와 비반전증폭된 신호를 비교함에 의해 데이타를 재생함으로써 재생신호의 레벨변동에 영향되지 않고 데이타를 정확히 재생할 수 있는 효과를 갖는다.The data reproducing apparatus according to the present invention inverts / non-inverts amplified derivative signals and reproduces the data by comparing the inverted-amplified signals with the non-inverted amplified signals, thereby accurately correcting the data without being affected by the level fluctuation of the reproduced signals. It has an effect that can be played back.
