| Zusammenfassung: | A deflection apparatus with raster distortion correction, comprises a horizontal deflection circuit with a deflection winding, with a S-capacitor (C09), which is coupled in series to the deflecting winding, with at least two further capacitors (C10, C11) and with a switching circuit. By comparing a first comparison signal with a second comparison signal, the switching circuit selectively connects the at least two further capacitors (C10, C11) in parallel to the S-capacitor (C09) during each trace and retrace interval. By integrating a horizontal flyback signal a replacement signal SR is provided and generates the first comparison signal. |
