Abstract
PROCEDIMIENTO PARA LA TRANSFORMACION DE SEÑALES VOCALES SUBDIVIDIDAS, EN SECCIONES DE SEÑALES, PARA LA RETRANSMISION CODIFICADA. CONSISTE EN DISLOCAR TEMPORALMENTE CADA UNA DE LAS SECCIONES DE SEÑALES (T) POR ENTRADA Y SALIDA DE LECTURA DENTRO Y FUERA DE ALMACENES CON VELOCIDADES DE ENTRADA Y SALIDA DIFERENTES. LAS SECCIONES TEMPORALES (T<U) QUE SE OBTIENEN SE EMPLEAN PARA LA RETRANSMISION DOBLE DE LAS PARTE DE SEÑALES EN LA REGION DE LOS PUNTOS DE CHOQUE DE CADA SECCION DE SEÑAL DE MODO QUE EL DESARROLLO ORIGINAL DE LA SEÑAL SE MANTIENE EN LOS LIMITES DE CADA SECCION DE SEÑAL EN LA SEÑAL CODIFICADA. EN EL LADO DE RECEPCION, SE SUPRIMEN LAS SECCIONES DE TIEMPO (T<U).
