Abstract

2.1 EN UN EQUIPO CONOCIDO SE ENCUENTRAN SOBRE LA PANTALLA RECEPTORA (1) DEFINIDOS A TRAVES DE UNA MUESTRA DE REJILLA LOS PUNTOS DE IMAGEN (K), PARA QUE SE AVERIGUE LA CORRIENTE DE CORRECCION Y PUEDA SER CONDUCIDA A UNA BOBINA DE DEFLECCION. LA MISION ES GARANTIZAR QUE EL VALOR NOMINAL (IN) DE LA CORRIENTE (IK) PARA UN PUNTO DE IMAGEN DETERMINADO (KN) SE ALCANZA EXACTAMENTE EN LA POSICION DE ESOS PUNTOS DE IMAGEN. 2.2 EL PUNTO DE PRINCIPIO (SP) PARA EL PROCESO DE CORRECCION PARA UN PUNTO DE IMAGEN (KN) SE ENCUENTRA EN UN VALOR TAL (TO) ANTES DEL PUNTO DE IMAGEN (KN-1), QUE EL TIEMPO DE FUNCIONAMIENTO ES NIVELADO O IGUALADO EN UN AMPLIFICADOR Y EL VALOR NOMINAL (IN) DE LA CORRIENTE DE CORRECCION (IK) PERMANECE EXACTO EN EL CORRESPONDIENTE PUNTO DE IMAGEN DISPUESTO. 2.3 ES ESPECIALMENTE INDICADO PARA LA CORRECCION DE LA CONVERGENCIA EN UN APARATO DE TELEVISION DE PROYECCION.
