Abstract

TECNICA DE REDUCCION DEL RUIDO EN PANELES LATERALES PARA TELEVISION AVANZADA COMPATIBLE. UN SISTEMA DE TRATAMIENTO DE SEÑAL DE VIDEO QUE USA UNA TECNICA DE COMPRESION-EXPANSION DE AMPLITUD PARA REDUCIR LOS EFECTOS DEL RUIDO DE TRANSMISION. EL DISPOSITIVO DE COMPRESION-EXPANSION INCLUYE UN COMPRESOR (12) NO LINEAL DE AMPLITUD DE TRANSMISOR PARA AMPLIFICAR PEQUEÑAS SEÑALES Y COMPRIMIR GRANDES SEÑALES. UN RECEPTOR INCLUYE UN DISPOSITIVO DE EXPANSION DE AMPLITUD CON UNA FUNCION DE TRANSFERENCIA INVERSA. EL COMPRESOR NO LINEAL (12) GENERA FRECUENCIAS FUERA DE BANDA QUE SON ELIMINADAS POR UN FILTRO (14) DE SALIDA DEL TRANSMISOR, QUE DA LUGAR A DEFORMACION DE LA SEÑAL. PARA COMPENSAR DICHA DEFORMACION, EL TRANSMISOR DUPLICA CIERTOS CIRCUITOS DE TRATAMIENTO DEL RECEPTOR INCLUYENDO EL DISPOSITIVO DE EXPANSION (16) DE AMPLITUD DEL RECEPTOR Y UN FILTRO (18, 20, 22) PARA GENERAR UNA SEÑAL DE PREDICCION.
