Abstract
UNA FUENTE DE CORRIENTE CONTROLABLE EN UN CIRCUITO AKB (70) APLICA UNA CORRIENTE DE MEDICION (IM) A UN AMPLIFICADOR ACCIONADOR DE TUBO RECEPTOR DE TELEVISION (50) DURANTE LINEAS SELECCIONADAS DEL INTERVALO VERTICAL DE UNA SEÑAL DE ENTRADA DE VIDEO PARA INDUCIR UNA CORRIENTE DE HAZ EN UN TUBO RECEPTOR DE TELEVISION (40) ACOPLADO AL AMPLIFICADOR ACCIONADOR. UN CIRCUITO COMPARADOR (100, 102, 104) COMPARA MUESTRAS (S5) DE LA CORRIENTE DE HAZ (IK) OBTENIDA DURANTE LA LINEAS SELECCIONADAS CON UNA SEÑAL DE REFERENCIA (VR) Y APLICA UNA CORRIENTE DE CORRECCION (IQ) AL AMPLIFICADOR ACCIONADOR (50) PARA REGULAR UN PARAMETRO (POR EJEMPLO, NIVEL NEGRO) DE IMAGENES VISUALIZADAS POR EL TUBO RECEPTOR DE TELEVISION (40). UNA FUENTE DE SEÑAL (HB, R2) ACOPLADA A LA FUENTE DE CORRIENTE DE MEDICION (82, 90, 92, 96) INHIBE LA PRODUCCION DE LA CORRIENTE DE MEDICION (IM) DURANTE LAS PARTES DE RECONSTITUCION DE LAS LINEAS SELECCIONADAS Y PERMITE LA PRODUCCION DE CORRIENTE DE MEDICION (IM) DURANTE LAS PARTES DE RECONSTITUCION DE LAS LINEAS SELECCIONADAS. VENTAJOSAMENTE, LA FUENTE DE SEÑAL PREVE LA SUPRESION DE ARTEFACTOS VISUALES DEBIDO A LA OPERACION AKB CUANDO SE USAN TUBO RECEPTORES DE PROYECCION O DE VISION DIRECTA DE U N TIPO EN EL QUE LA CORRECCION DE PUNTEAMIENTO NO SE APLICA DURANTE LOS INTERVALOS DE RECONSTITUCION DE LINEA.
