Patent ID: 7233118

Claim:
A line deflection circuit for a television receiver comprising: a deflection coil; an S capacitor for S correction of the linearity of the deflection, and being connected in series with the deflection coil; a network for changing the picture aspect ratio over the linearity of the line deflection, and comprising an inductance and a capacitance connected in series, wherein the network is tuned to approximately the line trace period; and a switch coupled to the network and operative to switch the network between an operative and a non-operative state; wherein, the network in its operative state is connected in parallel to the S capacitor; and the deflection circuit comprises: a bridge modulator for vertical-frequency modulation of the amplitude of the line deflection current for east/west pincushion equalization with a first bridge coil part in series with the S capacitor and a second bridge coil part in series with a second S capacitor between a terminal of the first S capacitor and flyback capacitors; and, another capacitance connected in series with the first bridge coil part for increasing the oscillation frequency formed by the first S capacitor and the first bridge coil part.
