Abstract

Un circuito para corregir la distorsión de almohadilla este-oeste, para receptores de televisión en color, que utiliza un modulador diodo dispuesto en el lado del secundario del transformador de deflexión horizontal. Caracterizado porque la tensión de alimentación principal (1) con sus (terminales E, F) producida por el modulador diodo, y porque la etapa de deflexión horizontal (terminales G, H) está conectada a los dos puntos de conexión exteriores (C, F) de este dispositivo serie.
