Abstract

EL INVENTO SE REFIERE A UN SISTEMA DE TRANSMISION DIGITAL EN LA QUE LA SEÑAL (L) DE CANAL INTERVIENE MEDIANTE UNA MATRIZ DE CONEXION DIGITAL EN LA ENTRADA DE LOS MULTIPLEXORES, QUE CENTRALIZA LA SEÑAL DE CANAL L'' (MENOR O IGUAL) L EN FRECUENCIA MULTIPLEXORA Y QUE CEDE LA SEÑAL DE SALIDA EN UNA DIRECCION DE M (MENOR O IGUAL) L. ESTA CARACTERIZADO POR QUE EL MULTIPLEXOR ESTA FORMADO POR UNA CASCADA DE VARIOS MULTIPLEXORES INDIVIDUALES (MUX1 ... MUX ) ALINEADOS Y CONECTADOS POR ESCALONES Y PORQUE SE INTERCALA UNA MATRIZ DE CONEXION (SM 1 ... SM ) DELANTE DE LAS ETAPAS MULTIPLEXORAS INDIVIDUALES, PORQUE PRESENTA EN LA ETAPA X PARA 1 (MENOR O IGUAL) X (MENOR O IGUAL) LA MATRIZ DE CONEXION (SMX), SEÑAL DE ENTRADA (LX-1) Y SEÑAL DE SALIDA (LX-1), PORQUE LA SALIDA (LX-1) DE LA MATRIZ DE CONEXION CON LA ENTRADA (LX-1) DEL MULTIPLEXOR (MUXU) CONECTADO A CONTINUACION INDICA LA SALIDA LX Y PORQUE LA ENTRADA DE LA MATRIZ DE CONEXION (LX-1) SE CONECTA CON LA SALIDA (LX-1) DE MULTIPLEXORES PARCIALES INTERCALADOS PARA X=1 (DESMULTIPLEXORES DEMUX). UN DISPOSITIVO CORRESPONDIENTE ES UTILIZABLE PARA UN SISTEMA DE TRANSMISION DE RETROCESO. ADEMAS LA INVERSION DE LA DIRECCION TRANSFORMA EL MULTIPLEXOR EN DEMULTIPLEXOR.
