Abstract

SISTEMA DE TELEVISION POR COLOR LETTERBOX SE TRANSMITEN INFORMACIONES ADICIONALES POR RAZONES DE COMPATIBILIDAD CON UNA AMPLITUD CLARAMENTE REDUCIDA, EN DONDE LAS PARTES DE FRECUENCIA BAJA TIENEN UNA AMPLITUD RELATIVAMENTE GRANDE. POR ELLO, SE REDUCE SIN EMBARGO LA RELACION SEÑAL/RUIDO Y EN RECEPTORES DE TELEVISION CONOCIDOS APARECEN ANOMALIAS DE SINCRONIZACION. MEDIANTE LA TRANSMISION DE LAS INFORMACIONES ADICIONALES EN FORMA DE UNA MODULACION DE BANDA LATERAL RESIDUAL DEL SOPORTE DE COLOR SE PUEDE AUMENTAR LA AMPLITUD DE LAS INFORMACIONES ADICIONALES SIN QUE EN LOS RECEPTORES DE TELEVISION CONOCIDOS APAREZCAN ANOMALIAS DE SINCRONIZACION. PARA LA FORMACION DE UN FLANCO NYQUIST EN EL SOPORTE DE COLOR SE PUEDEN UTILIZAR CON VENTAJA EL PASO DE FRECUENCIA DE FILTROS ZF CONOCIDOS. CUANDO SE UTILIZA UNA FASE COMO FASE V CONSTANTE DEL SOPORTE DE COLOR, LAS POSIBLES ANOMALIAS DE LA RECEPCION COMPATIBLES SON RELATIVAMENTE PEQUEÑAS.
