Abstract
"REDE LOCAL QUE FAZ PARTE DE SISTEMA DE TV A CABO". Trata-se de uma rede local (10) , que faz parte de um sistema de TV a cabo, a qual inclui saídas de assinante (21), das quais sinais podem ser transmitidos na direção de retorno a uma extremidade de entrada (11) do sistema dentro de uma faixa de frequência de portadora predeterminada. A rede (10) é dotada de uma unidade de redução de ruído (23) que compreende uma entrada (24), ligada às saídas de assinante (21), uma saída (27), ligada à extremidade de entrada (11), uma série de filtros de passagem de faixa (28 - 31), ligados à entrada (24) e que têm faixas de passagem mutuamente diferentes dispostas dentro da faixa de frequencia de portadora, e uma série correspondente de detectores (32 - 35), que são dispostos, cada um deles, de modo a compararem o nível de energia do sinal de saída de um dos filtros (28 - 31) com pelo menos um nivel de referência predeterminado e de modo a transmitirem sinais lógicos, dependendo do resultado da comparação, a uma unidade de controle lógico (36) , que é disposta de modo a determinar se estes sinais satisfazem determinadas condições armazenadas na unidade de controle (36) e de modo a transmitir um sinal de controle, dependendo dela, a um circuito de controle controlável (26), que é conectado em uma linha (25) distinta, que funciona para transmitir sinais da entrada (24) à saída (27), e que é disposta de modo a permitir que sinais passem através dela somente quando recebe um sinal de controle da unidade de controle (36), que indica que os sinais lógicos recebidos pela unidade de controle (36) satisfazem as condições armazenadas na unidade.
