ABSTRACT:
A line deflection circuit for a television receiver having a deflection coil, an S capacitor for S correction of the linearity of the deflection, the capacitor being connected in series with the deflection coil, and having means for changing over the linearity of the line deflection current for a change of the picture aspect ratio, wherein the means for changing the picture aspect ratio comprise a network formed by an inductance and a capacitance which are connected in series, wherein the network is tuned to approximately the line trace period, wherein a switch is provided to switch the network between an operative and a non-operative state, and wherein the network in its operative state is connected in parallel to the S capacitor.
