Abstract

UN PRIMER BUCLE DE FRECUENCIA CERRADA (12) GENERA UNA PRIMERA SEÑAL DE SINCRONIZACION (EN 17) EN UNA PRIMERA FRECUENCIA SINCRONIZANTE (1FH) CORRESPONDIENDO A UN COMPONENTE HORIZONTAL DE SINCRONIZACION (EN 13) EN UNA SEÑAL DE VIDEO (EN 11). UN CIRCUITO DE CONVERSION (56) DERIVA DESDE LA PRIMERA SEÑAL DE SINCRONIZACION (EN 17) UNA SEGUNDA SEÑAL DE SINCRONIZACION (EN 61), TENIENDO UNA SEGUNDA FRECUENCIA (2FH) EN UN MULTIPLO DE LA PRIMERA FRECUENCIA Y SUJETO A UNA VARIACION EN FRECUENCIA EN UNA PROPORCION CORRESPONDIENDO A LA PRIMERA FRECUENCIA. UN SEGUNDO BUCLE DE FASE CERRADA (62) RECIBE LA SEGUNDA SEÑAL DE SINCRONIZACION (EN 61), QUE PUEDEN SER ASIMETRICAS DENTRO DEL PERIODO DE LA PRIMERA SEÑAL DE SINCRONIZACION (EN 17), Y UNA SEÑAL DE REALIMENTACION (EN 73) DE ACUERDO CON LA SEGUNDA FRECUENCIA, E INCLUYE UN OSCILADOR CONTROLABLE (66) PARA GENERAR UNA SEÑAL SINCRONIZADORA HORIZONTAL SUAVE (EN 67) EN LA SEGUNDA FRECUENCIA. EL SEGUNDO BUCLE DE FASE CERRADA TIENE UNA RESPUESTA DE BUCLE CARACTERISTICA, DETERMINADA POR UN FILTRO DE BAJO PASO (63), PREVINIENDO AL OSCILADOR CONTROLADO DE TENSION (66) EL CAMBRER DE FRECUENCIA TAN DEPRISA COMO EL NIVEL DE VARIACION DE LA SEGUNDA SEÑAL DE SINCRONIZACION (EN 61). ESTO DIRIGE LA SEÑAL DE ERROR PARA EL OSCILADOR CONTROLABLE (66) HACIA UN VALOR MEDIO, RESULTADO EN UNA SEÑAL SINCRONIZADORA SIMETRICA CORREGIDA EN LA SEGUNDA FRECUENCIA. UN PASO DE DEFLECCION DE SALIDA HORIZONTAL (68) PUEDE SER ACOPLADO AL SEGUNDO BUCLE DE FASE CERRADA (62) PARA UNA EXPLOTACION HORIZONTAL SINCRONIZADA DE ACUERDO CON LA SEGUNDA FRECUENCIA. NO SE NECESITA UNA CIRCULACION PROCESADORA DE SEÑALES ADICIONAL PARA CORREGIR LA SIMETRIA DE LA PRIMERA SEÑAL DE SINCRONIZACION GENERADA POR EL PRIMER BUCLE DE FASE CERRADA O LA SIMETRIA DE LA SEGUNDA SEÑAL DE SINCRONIZACION DERIVADA MEDIANTE EL CONVERTIDO.
