Abstract

Un método mejorado de generar señales de factor de correción para un tubo de rayos catódicos, método que comprende las etapas de: dividir la pantalla del tubo de rayos catódicos en un número de áreas prefijado; presentar visualmente un diseño de ensayo en cierto número, menor que dicho número prefijado, de puntos seleccionados en la pantalla; derivar unos valores para las señales de factor de corrección en los puntos en que se presentó el diseño de ensayo; y usar los valores derivados para determinar unos valores de señales de factor de corrección para ostras áreas asociadas de la pantalla.
