Abstract

2.1. EN UN GRABADOR DE VIDEO ES EFECTIVO UN CIRCUITO ACC (AUTOMATIC CHROMA CONTROL), QUE DEBIDO A LA EVALUACION DE LA AMPLITUD DE LA SEÑAL SINCRONA DE COLOR ESTABILIZA LA AMPLITUD DE LA PORTADORA DE COLOR. CONDICIONADO POR EL CAMBIO DEL CABEZAL, PUEDE DARSE EL CASO QUE AL COMIENZO DE LA IMAGEN, APAREZCAN PERTURBACIONES EN EL BORDE SUPERIOR DE LA IMAGEN EN FORMA DE CENTELLEOS. EL COMETIDO ES LA DE ELIMINAR SEMEJANTES PERTURBACIONES EN FORMA DE CENTELLEOS. 2.2. LA CONSTANTE DE TIEMPO (T) DEL CIRCUITO ACC SE CONMUTA AL COMIENZO DE LA IMAGEN DURANTE LA TRANSFERENCIA DEL RAYO ELECTRONICO A UN VALOR MAS PEQUEÑO (T2). 2.3. ESPECIALMENTE PARA UN GRABADOR DE VIDEO VHS.
