Abstract

PROCEDIMIENTO PARA LA ELEVACION COMPATIBLE DE LA DISOLUCION EN UN SISTEMA DE TELEVISIONES EN COLORES CON MODULACION OFFSET DEL EMISOR Y CON DEMODULACION OFFSET DEL RECEPTOR CON UNA SEÑAL DE LA REFERENCIA, QUE DURANTE EL TIEMPO DEL RETROCESO VERTICAL TRANSMITE. CONFORME AL INVENTO CONTIENE LA SEÑAL DE LA REFERENCIA, DOS OSCILACIONES (S1,S2) DE DIFERENTE FRECUENCIA, DE LA QUE LA PRIMERA (S1) CONTIENE UNA INFORMACION DE FASE SOBRE LA ADICION ESPECTRAL, DEL RECEPTOR Y LA SEGUNDA (S3) CONTIENE UNA INFORMACION SOBRE LA FASE DE MODULACION OFFSET. DE ESE MODO SE CONSIGUE UNA DEMODULACION DE LA COMPATIBILIDAD PARA LAS NORMAS CONSISTENTES DE TELEVISION.
