Abstract

EN UN GENERADOR DE DIENTE DE SIERRA VERTICAL DE UN CIRCUITO DE DEFLEXION VERTICAL ACOPLADO DE CORRIENTE CONTINUA, UN AMPLIFICADOR DE DEFLEXION VERTICAL (11A, FIG.1C) GENERA UNA SEÑAL DE DIENTE DE SIERRA. SE DETERMINAN MAGNITUDES DE LA SEÑAL DE DIENTE DE SIERRA EN INSTANTES PRIMERO (FINAL DE RETORNO) Y SEGUNDO (DURANTE LINEA 210, FIG.2B) DE UN PERIODO DE LA TRAZA DE ACUERDO CON SEÑALES PRIMERA (VHIGH, FIG.1B) Y SEGUNDA (VLOW FIG.1B) RESPECTIVAMENTE. LAS SEÑALES DE CORRIENTE CONTINUA PRIMERA Y SEGUNDA SE AJUSTAN DURANTE EL FUNCIONAMIENTO PARA CONTROLAR LA ALTURA DE TRAMA Y EL CENTRADO DE TRAMA DE MODO QUE MIENTRAS SE AJUSTA LA ALTURA DE TRAMA, EL CENTRADO DE TRAMA NO SE VEA MAYORMENTE AFECTADO, Y VICEVERSA.
