Abstract

Un sistema multicanal de transmisión de señales que comprende una línea de uno o más repetidores intermedio adaptados para transmisión simultánea de dos o más señales independientes diseñado para cumplir un límite máximo dado para ruido e interferencia generada dentro o captada por dicha línea y repetidores y caracterizado en que dichos repetidores consisten de amplificadores de regeneración negativa, estando el número de repetidores y el grado de regeneración negativa en cada uno de dichos repetidores, proporcionado de tal modo, que con un repetidor de una potencia dada, la potencia de señal total permisible a la salida del repetidor es independiente de la longitud de dicha línea.A multi-channel signal transmission system that comprises a line of one or more intermediate repeaters adapted for simultaneous transmission of two or more independent signals designed to meet a given maximum limit for noise and interference generated within or captured by said line and repeaters and characterized in that said repeaters consist of negative feedback amplifiers, the number of repeaters and the degree of negative feedback in each of said repeaters being proportioned in such a way that with a repeater of a given power, the total signal power allowable to the Repeater output is independent of the length of that line.
