  • CATV system and automatic noise controller
    Publication number: 20070288981
    Abstract: The present invention relates to a CATV circuit with an automatic noise controller and a CATV system using the CATV circuit. The CATV circuit is used for automatically reducing upstream noises occurred in a CATV circuit for bidirectional communications between a control center and a home terminal. A variable attenuation method is applied to the CATV circuit, and a noise level measurement method is applied to measure the upstream noise level and control the attenuation rate according to the measured noise level.
