Abstract

UN SISTEMA DE TRANSMISION DE UNA SEÑAL DE VIDEO INCLUYE UN CIRCUITO DE COMPRESOR-EXTENSOR ADAPTABLE PARA MEJORAR LA VELOCIDAD DE SEÑAL-A-RUIDO DE SEÑALES TRANSMITIDAS. UN COMPRESOR-EXTENSOR (510) EN EL TRANSMISOR, Y UN COMPRESOR-EXTENSOR INVERSO (60) CORRESPONDIENTE EN EL RECEPTOR, ESTAN MONTADOS PARA DAR UNA PLURALIDAD DE CARACTERISTICAS DE TRANSFERENCIA DE COMPARACION SELECTIVA. LA SELECCION (530, 660) DE OTRAS PARTICULAS DE LAS CARACTERISTICAS DE TRANSFERENCIA, RESPONDE A POR EJ., VALORES PREVISTOS (550, 570, 630, 640) DE SEÑAL NORMAL.
