Abstract

UN SISTEMA DE DESVIACION, COMPRENDE UN AMPLIFICADOR DE GANANCIA VARIABLE (32) PARA UN COMPONENTE DE LUMINANCIA (V1) DE UNA SEÑAL DE VIDEO. UN PRIMER DIFERENCIADOR (34) DIFERENCIA EL COMPONENTE DE LUMINANCIA AMPLIFICADO. UN AMPLIFICADOR DE SALIDA (36), MODULA LA VELOCIDAD DE EXPLORACION DEL RAYO DE UN RAYO DE ELECTRON AL ENERGIZAR UN YUNQUE DE DESVIACION HORIZONTAL AUXILIAR (20), EN RESPUESTA AL COMPONENTE DE LUMINANCIA DIFERENCIAL (V3). UN SEGUNDO DIFERENCIADOR (38), DIFERENCIA EL COMPONENTE DE LUMINISCENCIA DIFERENCIADO (V3). UN INTEGRADOR (40), INTEGRA EL COMPONENTE DE LUMINANCIA DIFERENCIADO DOS VECES (V4). LA SALIDA DEL INTEGRADOR (40) ES UNA SEÑAL DE CONTROL DE GANANCIA (V5). EL AMPLIFICADOR DE GANANCIA VARIABLE (32), TIENE UNA GANANCIA QUE VARIA EN RESPUESTA A LA SEÑAL DE CONTROL DE GANANCIA (V5) . LA GANANCIA VARIA INVERSAMENTE CON EL CONTENIDO DE FRECUENCIA DEL COMPONENTE DE LUMINANCIA (V1). EL SEGUNDO DIFERENCIADOR (38) E INTEGRADOR (40), FORMAN UN BUCLE DE REALIMENTACION. EL BUCLEDE REALIMENTACION TIENE UNA CONSTANTE DE TIEMPO SUFICIENTEMENTE GRANDE RELATIVA A TRANSICIONES DE NIVEL DEL COMPONENTE DE LUMINANCIA (V1) QUE LA SEÑAL DE DESVIACION (V3) CORRESPONDE A LA PRIMERA DERIVADA DEL COMPONENTE DE LUMINANCIA (V1) INDEPENDIENTE DE LA GANANCIA VARIABLE.
