Abstract

본 발명은 전기적으로 노이즈가 심각한 환경에서 입력되는 노이즈를 효과적으로 제거하기 위한 전동차용 디지탈 입력신호 처리회로에 관한 것으로, 잡음을 포함하는 신호가 입력되어 상기 잡음을 제거한 신호를 출력하기 위한 전동차용 입력신호처리회로에 있어서, 상기 잡음을 포함하는 신호가 입력되고, 주파수 통과특성이 다른 적어도 둘 이상의 필터(10-1,10-2); 및 상기 필터들로부터 출력되는 신호를 비교하여 출력하는 비교기(20-1,20-2)를 포함함을 특징으로 한다. 본 발명에 의하면 하나의 입력신호를 저주파필터 및 고주파필터에 동시에 통과시킴으로써, 비교적 단순한 회로를 이용하여 노이즈가 심각한 상황에서도 효과적으로 노이즈를 제거할 수 있는 잇점이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital input signal processing circuit for a vehicle for effectively removing noise input in an environment in which electrical noise is severe. CLAIMS 1. A processing circuit comprising: at least two filters (10-1, 10-2) having a signal including the noise and having different frequency pass characteristics; And comparators 20-1 and 20-2 for comparing and outputting signals output from the filters. According to the present invention, by simultaneously passing one input signal through a low frequency filter and a high frequency filter, it is possible to effectively remove the noise even in a serious noise situation by using a relatively simple circuit.
