Abstract

PERFECCIONAMIENTOS INTRODUCIDOS EN UN DISPOSITIVO DE SEPARACION DE SEN/AL EN UN SISTEMA DE TRATAMIENTO DE SEN/AL DE TELEVISION.CONSISTENTES EN UN SISTEMA DE SEPARACION DE SEN/ALES PARA SEPARAR COMPONENTES DE SEN/AL INTERCALADAS EN FRECUENCIA DE UNA SEN/AL DE VIDEO, UNA DE LAS CUALES ESTA MODULADA EN FORMA DE SEN/ALES DE BANDA LATERAL DOBLE DE UNA FRECUENCIA SUBPORTADORA; UNA SEN/AL DE VIDEO ES MUESTREADA POR UN CONVERTIDOR DE ANALOGICO A DIGITAL; LAS MUESTRAS DE SEN/AL RESULTANTES SE APLICAN A UN FILTRO DE PASO DE BANDA QUE PRODUCE UNA SEN/AL FILTRADA, RESTRINGIDA A UNA BANDA DE PASO DADA DE LA BANDA DE VIDEO ORIGINAL SOBRE LA QUE ESTA MODULADA LA COMPONENTE MODULADA DE BANDA LATERAL DOBLE. LA INFORMACION FILTRADA EN LA BANDA DE PASO ES FILTRADA POR UN FILTRO DE PEINE QUE COMPRENDE UN REGISTRO DE DESPLAZAMIENTO Y UN CIRCUITO COMBINADOR DE SEN/ALES Y QUE FUNCIONA SOBRE UNAS SELECCIONADAS DE LAS MUESTRAS FILTRADAS POR EL FILTRO DE PASO DE BANDA EN RESPUESTAA UNA SEN/AL DE RELOJ DE MUESTREO SECUNDARIO, CUYA FRECUENCIA ES MENOR O IGUAL QUE LA FRECUENCIA DE SUBPORTADORA. LAS MUESTRAS DEJADAS PASAR POR EL FILTRO DE PEINE, CORRESPONDEN A UNA DE LAS COMPONENTES DE SEN/AL TERCALADAS.
