Abstract

RECEPTOR DE TELEVISION EN COLOR PROVISTO DE UN FILTRO DE PEINE QUE TIENE UNA SALIDA PARA PROPORCIONAR SEÑALES DE INFORMACION DE LUMINANCIA Y DE CROMINANCIA SEPARADAS. CARACTERIZADO PORQUE INCLUYE UN SEPARADOR DE IMPULSOS DE SINCRONISMO ACOPLADO A LA SALIDA DEL FILTRO DE PEINE PARA DERIVAR LOS IMPULSOS DE SINCRONISMO DE LA SEÑAL DE INFORMACION DE LUMINANCIA SEPARADA, PRESENTANDO DICHA SEÑAL DE INFORMACION DE LUMINANCIA UNA REDUCCION EN LA AMPLITUD DE LOS COMPONENTES DE LA SEÑAL DE INTERFERENCIA CON RESPECTO A LA SEÑAL DE VIDEO; PORQUE DICHA SEÑAL DE INFORMACION DE LUMINANCIA SEPARADA TIENE UNA RESPUESTA DE FRECUENCIA QUE PRESENTA COMPONENTES DE SEÑAL EN POSICIONES DEL ESPECTRO ESPACIADAS REGULARMENTE; Y PORQUE LA SEÑAL DE INFORMACION DE CROMINANCIA SEPARADA TIENE UNA RESPUESTA DE FRECUENCIA QUE PRESENTA COMPONENTES DE SEÑAL DIFERENTES DE LAS COMPONENTES DE LA SEÑAL DE LUMINANCIA.
