Abstract
이로 인해 필터에서의 신호 지연이 상당히 감소할 뿐만 아니라 또한 그 주파수가 동작 범위 내에서 동일하지 않게 되고, 차단 주파수 아래에 있는 주파수 성분이 이에 따라 더 많이 감쇠되게 되므로, 작동해야 할 경우(triggering cases)를 조기에 인식할 수 있을 뿐만 아니라 작동하지 않은 경우(non-triggering cases)도 신뢰성 있게 인식할 수 있게 된다.
Description
도 1은 고체 전반음 원신호와 기존의 방법 및 본 발명의 방법에 따라 여과한 신호를 비교한 것이다.
도 2는 작동하지 않을 경우에 대한 여과된 신호의 상호 비교를 나타낸다.
도 3은 작동하지 않을 경우에 대한 여과된 신호의 상호 비교를 나타낸다.
도 4는 본 발명에 따른 필터의 주파수 응답을 나타낸다.
