Abstract

PERFECCIONAMIENTOS INTRODUCIDOS EN UN DISPOSITIVO DE SEPARACION DE SEÑAL EN UN SISTEMA DE TRATAMIENTO DE SEÑAL DE TELEVISION.LAS MUESTRAS NUMERICAS DE FRECUENCIA 4FSC PRODUCIDAS POR EL CONVERTIDOR (10) DE ANALOGICO EN NUMERICO SE APLICAN A LAS ENTRADAS DE UN PASO RETARDADOR (14) Y DE UN FILTRO NUMERICO (12) DE PASO DE BANDA. EL PASO RETARDADOR (14) PROPORCIONA UN RETARDO IGUALADOR O COMPENSADOR QUE CONCUERDA CON LOS RETARDOS ENCONTRADOS POR LAS SEÑALES ENTRE LA ENTRADA DEL FILTRO (12) DE PASO DE BANDA Y LA SALIDA DE UN INTERPOLADOR (16). EL FILTRO (12)PRODUCE SEÑALES DE SALIDA A UN REGIMEN DE 2FSC, QUE SE APLICA A UN FILTRO DE PEINE (20). ESTE INCLUYE UNA LINEA DE RETARDO (22) DE UN H, SINCRONIZADA A LA FRECUENCIA DE SEÑAL 2FSC, Y UN SUBSTRACTOR (24). ESTE SUBSTRACTOR PRODUCIRA SEÑALES DE CROMINANCIA FILTRADAS POR PEINE, A UNA FRECUENCIA DE SINCRONISMO DE 2FSC. LAS SEÑALES DE CROMINANCIA SE APLICAN TAMBIEN A LA ENTRADA DEL INTERPOLADOR (16).
