Abstract
SE DA A CONOCER UN SISTEMA DE TRANSMISION ELECTRICO, DONDE SE CONECTAN EN UNA RED (2) DE DISTRIBUCION DE BANDA AMPLIA UNA CENTRAL (1) Y UNA MULTIPLICIDAD DE APARATOS (26) TERMINALES, QUE PUEDEN RECIBIR SEÑALES DE TV Y DE AUDIO EMITIDAS A PARTIR DE LA CENTRAL Y SEÑALES INDIVIDUALES DE PARTICIPANTE, ASI COMO PUEDEN EMITIR LAS SEÑALES DE VALORACION HACIA LA CENTRAL (1). LA RED (2) DE DISTRIBUCION DE BANDA AMPLIA DISPONE DE UNA MULTIPLICIDAD DE AMPLIFICADORES (10) DE PARTICIPANTE, EN LOS QUE SE CONECTA UN GRUPO DE APARATOS (26) TERMINALES, Y DONDE SE UNEN DE FORMA RESPECTIVA CON UN EQUIPO (4) DE CANAL DE RETORNO. EL EQUIPO (4) DE CANAL DE RETORNO ESTA CONECTADO EN UNA CONDUCCION (21) DE DOS ALAMBRES, QUE SE UNE DE FORMA INMEDIATA CON LA CENTRAL (1). EL EQUIPO (4) DE CANAL DE RETORNO VALORA LAS SEÑALES EMITIDAS A PARTIR DEL GRUPO DE APARATOS (26) TERMINALES.
