Abstract
케이블 텔레비젼에 있어서, 화면의 열화현상을 방지하기 위하여 멀티 플렉서의 제어신호 입력단에 배타적 논리합 회로를 추가로 접속 채용하여 PN 코드 입력신호 FA 신호입력에 따라 배타적 논리합 회로에 의해 반전 또는 비반전중 제어된 어느 하나의 코드 입력신호만으로 멀티플렉서에 인가됨으로써 화면의 화질 열화를 방지하도록 한 케이블 텔레비전을 구현하였다.In cable television, an exclusive OR circuit is further connected to a control signal input terminal of a multiplexer to prevent screen degradation, and is controlled by an exclusive OR circuit according to a PN code input signal FA signal input. The cable television is implemented to prevent deterioration of picture quality by being applied to the multiplexer using only one code input signal.
