Abstract

SE PRESENTA UN APARATO DE REPRODUCCION MAGNETICA QUE USA UN MEDIO DE GRABACION MAGNETICO SOBRE EL CUAL SE GRABAN LAS SEÑALES DE FRECUENCIAS MODULADAS PRODUCIDAS MODULANDO LA FRECUENCIA DE UNA PORTADORA CON LAS SEÑALES DE VIDEO, Y QUE DEMODULA LAS SEÑALES REPRODUCIDAS DESDE EL MEDIO DE GRABACION MAGNETICA A SEÑALES DE VIDEO. EL APARATO INCLUYE UN CONVERSOR DE FRECUENCIA PARA PROVOCAR QUE LAS SEÑALES REPRODUCIDAS SE DESPLACEN HASTA UNA ZONA DE FRECUENCIA MAYOR Y UN DEMODULADOR FM DEL TIPO DE CONTEO DE PULSOS PARA MODULAR LAS SEÑALES REPRODUCIDAS QUE HAN SIDO DESPLAZADAS A LA ZONA DE FRECUENCIA MAYOR EN LAS SEÑALES DE VIDEO. ESTA DISPOSICION RESTRINGE LA MEZCLA DE LAS SEÑALES REPRODUCIDAS EN LAS SEÑALES DE VIDEO. ADEMAS LAS SEÑALES DE VIDEO SE REPRODUCEN CON UNA MENOR DISTORSION DE LA FORMA DE LA ONDA, CONSIGUIENDO UNA MAYOR CALIDAD DE IMAGEN.
