| Zusammenfassung: | A television centering circuit includes a non-linear conduction network coupled in series with an inductance. The series arrangement is conductively coupled in parallel with a horizontal deflection winding. A control circuit for the non-linear conduction network utilizes negative feedback to sense and control the current in the inductance when the current is of a first polarity, thereby regulating the average value of the current in the inductance and in the deflection winding to provide raster centering. |
